Hi, I've two questions about drawing marks on axis:
I'm trying to draw special (small square) marks on X axis (like the sample). Is it possible? I've line and stepline graphics with only 7 values in X axis.
I also trying to draw minor ticks (not minor lines) on Y axis. Is it possible? How can I define the interval, I'm interest on draw 10 minorticks per 1 MajorGridLine.
Thanks in advanced
Thanks, it works fine!!!
Unfortunately, the chart doesn't support tickmarks out of the box. The workaround is to handle FillSceneGraph event and draw the tickmarks there. Here's a code example how you can do this for the Y axis. You can adapt the same approach for the Y axis.
private void ultraChart1_FillSceneGraph(object sender, FillSceneGraphEventArgs e){ if (e.Grid.Count == 0) return;
IAdvanceAxis xAxis = (IAdvanceAxis)e.Grid["X"]; IAdvanceAxis yAxis = (IAdvanceAxis)e.Grid["Y"]; int min = Convert.ToInt32(xAxis.Minimum); int max = Convert.ToInt32(xAxis.Maximum); int size = 6;
for (int i = min; i < max; i++) { Box mark = new Box(new Rectangle( (int)xAxis.Map(i) - size / 2, (int)yAxis.MapMinimum - size / 2, size, size )); mark.PE.Fill = Color.Red; e.SceneGraph.Add(mark); }}
