ViewXY - Axis.Title Z order

The axis' labels Title and Units seem to be placed behind the axis:
- AxisTitleClipping.png (3.02 KiB) Viewed 22690 times
Code: Select all
axis.Units.Text = "[Units]";
axis.Units.Fill.Color = Color.Red; // Red for demonstration, White for production
axis.Units.Fill.GradientColor = Color.Red;
axis.Units.Fill.GradientFill = GradientFill.Solid;
axis.Units.Fill.Style = RectFillStyle.ColorOnly;
axis.Units.DistanceToAxis = 7;
axis.Units.HorizontalAlign = XAxisTitleAlignmentHorizontal.Center;
axis.Units.VerticalAlign = XAxisTitleAlignmentVertical.Bottom;
Is there a way to influence the Z order of the Title/Units so that the Text can override the axis scale numbers?
(The old library did it this way, LightningCharts as the replacement is expected to behave the same, according to my boss...)

LightningChart renders the axis labels, titles and units in a batch for performance reasons. That means, first the fills are rendered, then the texts.
Please use Annotations to show the texts with a fill, retaining the fill / text order you prefer.

Annotations seem to be rendered behind the axis aswell:

Am I missing a property? Or did I misunderstand you?

Sorry I gave wrong info about annotations. They really seem be rendered behind the axes.
Series titles are rendered after the axes, so that would be they way to render text over axis value labels.
Code: Select all
pls.Title.Visible = true;
pls.Title.MouseInteraction = false;
pls.Title.Fill.Color = Color.Red;
pls.Title.Fill.GradientColor = Color.Red;
pls.Title.Fill.Style = RectFillStyle.ColorOnly;
pls.Title.Text = "My units text";
pls.Title.Color = Color.Yellow;
pls.Title.LimitInsideGraphMargins = false;
pls.Title.LockAutoPosition = false;
pls.Title.AutoPlacement = false;
pls.Title.HorizontalAlign = AlignmentHorizontal.Center;
pls.Title.VerticalAlign = AlignmentVertical.Bottom;
pls.Title.Offset.Y = 40;
Here, pls is a series. You may want to use a dummy series, not an actual series containing data.
Then it becomes like this:
- Series title over the axis

I found another issue. It seems the title text of the PointLineSeries is trimmed on the right side:
- Bug_SeriesTitle.png (5.65 KiB) Viewed 22232 times
Code: Select all
PointLineSeries _unit;
_unit.Title.Text = " [" + strAxisUnit + "] ";
Tested in 6.5.6 and 6.5.7

The DirectX text measuring methods don't measure the trailing spaces.
DirectX-side code: rectText = dxFont.MeasureText(m_spriteText, text, FontDrawFlags.NoClip);
The rectangle size of the title is based on this this info.
I'm sorry it seems we can't fix it.
How about adding a white border around the title?
series.Title.Border.Style = Outer
series.Ttile.Border.Color1 = White
series.Title.Border.Color2 = White
series.Title.Border.Width = 3

Hmmm, this will only work for small borders as it will otherwise overwrite the axis and the ticks to the top and not just the numbers.
But I'll accept it as a workaround.
