I am sorry... I snipped the wrong license keys... those were from 2016... apparently I forgot it is already 2017...


EDIT: DO NOT PUT LICENSE KEYS IN FORUMS

To whom it may concern: I have recently added the license keys from my ALF file into License Manager, but am still getting a LIcense Not Activated watermark error on all my charts. I have attached a snip of both the output window of License Manager showing my license keys imported from the ALF file ...

Hi, Pasi:

Thanks for the reply...! Looking forward to the new release!

Hi, LightningChartTeam: With the latest v6.5.7 release, I noticed the release notes said that the ErrorYPlus and ErrorYMinus have been reversed... however, I am noticing this to be only the case for the Linear scale... they still seem reversed on the Logarithmic scale... I made a small demo project ...

Hi, Pasi:

Thanks for the reply... I will discuss that with my team.. more likely they won't want to bother if they know it requires extra resources to be allocated..

Hi: Is it possible to change how the symbol on the legend displays for a certain type of element? That is, it appears bar elements show with a line under them in the legend, whereas a point series shows as the symbol you mark it as in the point line series... the question is more if the bar could lo...

Wondeful! I will give this a try and let you know if i run into any additional problems...

Hi... Sorry for all these questions on the legend box lately... we successfully moved from our own WPF 'legend' back to the Arction legend (mainly to get it stored into the image file when using SaveToFile()). One difference I noticed between the two mainly is the WPF control's checkbox could be sel...

So it appears I have found a workaround.. I need to set the title's alignment to the right, followed by setting it immediately to the left, in order for things to work... If I just set it to the left, it doesn't align properly... but at least I think at this point i have something that works.... :/

So I'm still having trouble and confusion.... For some reason, in one chart, when I have the title on HorizontalAlign = Left, and setting a negative distance, it is moving the title to the left... on another chart it is moving it to the right... I've verified with the debugger that both axis titles ...

Ahhhh... ok, I see... the AfterRendering here is the key... sometimes i was getting 0 back for the rendering rectangle, and I was, for now, calling all my methods a second time to get this to happen... ok, now that I know about this, this might help in other cases where I sometimes see values as 0 e...

Hi... I am having a problem which I can't figure out the answer to... If I have a chart which I initially view (I use the OnLoaded event to fire the rendering of the chart), I initially will have no data shown, which means, when I do, I leave the ViewXY.Margins to be calculated automatically. When I...

Hi, all! Sorry for wasting your time.. I did a big more digging on the forum here and found that LineCollections are put into the LegendBox as well... :lol: As you can see in the graphs below, i use line collections to perform the separation of the chart into regions, rather than using the built in ...

Hello: I was trying to figure out how to best remove an item that pops up in my legend box that says Series Title, even though I was pretty sure I didn't make a series with that title... I have tried using different Categorizations... when i do BySeries, that string disappears, however, the items ar...

Hi, Pasi

Thanks for the reply... would that be a good idea though based on how many users might be writing their code based on how it actually works? If you were to modify its usage, that might break a lot of existing applications...?

Thanks again for being so responsive!

To whom it may concern: I was wondering if ErrorYPlus and ErrorYMinus were somehow reversed? It seems to go in the opposite intuitive direction of ErrorXPlus and ErrorXMinus.. I wrote a small program to demonstrate it... //Initializechart lightningChartUltimate1.BeginUpdate(); //GetXYview ViewXY cha...

Hi, Pasi:

Thank you so much for the reply!

To whom it may concern: I am running into an issue that I can see also with the SDK demos that ship with the product... for example, in the CutLineData example, you have a line you can drag across the screen... however, if you drag it from the far right, to the left really fast, you will see the lin...

Hi, in order to fix this for the time being, I just check all the tick marks, and fix any of them are not the first/last label, and they have a fractional part, I force all labels to be formatted with 1 decimal point... this seems to work fine now:

I will also mention I am using CustomTicks here, not auto formatted labels or MajorDivs....

I am currently noticing a visual issue with the tick marks overlapping the y axis title... I have checked the code to see that AutoAdjustMargins is enabled to true, but this is the view I sometimes see: YAxisTitle.PNG However, it isn't happening all the time, sometimes it looks fine: YAxisTitleGood1...

Hi, Pasi:

Thanks for the reply... sorry, I had forgotten about this post... i found a solution that seemed to work well, but I will keep this solution in mind should my way not prove efficient enough...

Thanks!

Hi, Pasi: If you don't get a chance to reply right away, that is ok... I think I have found what I need for now... I am going through each tick one by one, finding its location, and finding the bar series values which are connected to that tick... So something like: var eachTicksRegion = CalculateTi...

Hi, Pasi: Thanks for the suggestions... I am probably not going to go with the 90 degree solution as that would limit the height of the bar when our graphs are smaller... I am curious though, it seems like when I use this code: var barSeriesRects = barSeries.GetBarRectangles(); var barSeriesValues =...

Hi, Pasi: I am currently seeing an issue with the bar series labels getting cut off, persumably I am guessing the z order or layering order is such that bars added get a higher z order... [img] BarLabelsHidden.PNG [/img] You can see that the labels get covered up by the bars they are next to.. I am ...

HI, Pasi:

Was able to get to this part of our project finally, and everything seems to work perfectly... thank you for adding this support in 6.5.5!

Hi, Tero: Thank you for the reply... That is ok about the stack... we are either going to have the right click zoom action be either disabled completely or use ZoomOut and then detect if the zoom event is being called with a zoom out (the ranges passed into the event increase from the last time..) a...

Hi, Pasi: Thanks for the reply... I have tried the case of the PopStack style where it is kind of a cool idea to pop off the last known scale... However, I have a hesitation to use it until I am sure I know what is going on in a certain case... if I zoom in a few times, then click on one of our butt...

I am currently hooking into and using the Zoomed event which fires during a Zoom to manually adjust certain things like the bar's width on my bar graph.. We mainly are only using the action that occurs on dragging the mouse from left to right across the graph. However, I just noticed there is an opp...

So I think I mostly figured everything i needed out... I just changed the minimum range to 0.0 and everything seems adjusted now... I'm not quire sure how all the ranges should necessarily bet set, but everything looks pretty good.. I just have to figure out how to space the groups a little better, ...

An update... I played with this a little more and realized I wasn't setting the values correctly to advance the x coordinates... here is how I have it fixed now for that method: private void PositionBarsCorrectly() { var barSpacing = Chart.ViewXY.BarViewOptions.BarSpacing; // Find current screen coo...

Yes, thank you.. was able to validate this evening finally that this functionality is working...

Actually, it looks like we will be upgrading, so we will be able to take the 6.5.5 changes where I can have a different number of bars per graph... I just tried the .dll now, and it all works the way I would expect... so first off, thank you very much for releasing this so I can have a different num...

To whom it may concern... I have been working on a workaround to some of the issues I have been having with bar series graphs, and feel like I have gotten as close as I can, but I can't nail down whatever the issue is that I am having... in the 6.5.1 release of the software there is a problem with h...

For anyone interested, or still reading this post, this workaround also works great for custom ticks, when you need to specify a different div count rather than 1 for each tick location....

So i have recently downloaded the latest 6.5.5 maintenance dlls, but I am having a problem with the program saying the license keys are too old... is there a way to validate whether the licenses are still good or not? And if not, we are ready to renew them... please let me know what information you ...

Hi, Pasi:

Thanks for replying... is there a suggested post that you could direct me to that could get me started in the right direction of what properties, methods, etc I could use to best detect overlapping labels and write an algorithm to prevent this?

Thanks

Just to shoot out a quick question in case I missed it in the documentation someplace... is there a similar feature as there is for WinForms SeriesCollection where you can enable a SmartLabelController which will prevent series event markers from overlapping? If not, that is ok, I am just making sur...

Thank you kindly! That will be amazing once released.. I will look forward to it...!

Just as a reference, here is where I am with this currently as a visual: BarSeriesAnnotation.png And here is the code i cobbled together from various other examples: var series = (BarSeries) sender; // Get the current mouse position in screen coordinates.... var screenPosition = e.GetPosition(m_Char...

How could I implement the following: 1) Let's say I have three bar series, and two values in each series... 2) I would like to place a hover text tooltip when over a specific bar to show its value I know you can place a callback when the mouse enters the series, but I need to know which value in the...

Thank you for replying so timely!

I have been playing around with the BarSeries for quite some time, trying to figure out how to get what i want, but am not quite able to figure it out... Essentially, I am going to want something like the following: I have a list of states with their top resources, and I want the resources to repres...
