Hi
We are in the process of evaluating Infragistics charting capabilities. We are particularly interested in the heatmap chart. How do you disable or reduce the gridlines on the surface of the resultant chat? Disabling the gridlines on either axis only affects the axis of the chart not the chart surface as expected.
Thank you for your assistance.
try setting ColorModel.AlphaLevel = 255. if that isn't what you're looking for, try changing the value of the HeatMapChart.RenderQuality property.
Thank you for your help. I've tried changing the ColorModel.AlphaLevel = 255 and I've also tried changing the HeatMapChart.RenderQuality but that did not get rid of the grid lines.
I've attached a sample of the chart. We would like stop the grid lines from drawing on the surface of the chart and obtain a smooth color only chart. i.e. We want to be able to do the following:
i don't see any attachment here, so i'm wondering why you still have gridlines on your chart. could you provide a picture or some sample code?
Thanks! This looks better...
if you still see gridlines (drawn on the scene behind the chart data) in that version, try downloading the latest available hotfix.
removing the lines from the chart data is not entirely possible, but if you set ColorModel.ModelStyle = CustomSkin, you can add a PaintElement to the ColorModel.Skin.PEs collection, and the Stroke color of that PaintElement will be used in the chart. set it to a color between ColorModel.ColorBegin and ColorEnd and the lines will be less noticeable.
I saw this post and this is exactly what I need. I am currently using version 8.2 and does not see the fix. I still see gridlines on the graph. I only want the see the color surface but don't want any lines at all on the surface. Can you please advise?
ok, now i see the image and i checked out your project as well. my mistake earlier was that i thought you were using a 2D heatmap chart.
this is a bug. since Axis.Z.MajorGridlines.Visible = false, there shouldn't be gridlines there. i logged it (bug # BR32186) and fixed it, so it will be resolved in an upcoming hotfix as well as the release version of 8.2.
you can contact Infragistics Developer Support if you want to inquire about the status of this bug, or to be placed on the notification list for when the bug gets fixed.
I've attached the sample code that outputs the grid.
