Area and bar charts area a black blob

[Doug]

Hello,

When there are many x-axis values in our chart, it appears as all black. I think it is because of the lines that run vertically on the chart.

The screenshot attachments explain it better. In the first screenshot, there are 10800 x-axis values which means 10800 lines, so it's a black blob. In the second screenshot which has 360 x-axis values, you can see the individual black lines that I think are causing the problem. I think I just need to know which property toggles those lines on and off.

The chart is fine when it is converted to a line chart because it does not have these lines. We are using TChart v7.12, in Delphi 2007. Many thanks for any help.

Doug

Hi Doug,

Try these properties:

Code: Select all

  Series1.Pen.Visible:=false;  //bar series' vertical lines / area series' top tines
  Series1.AreaLinesPen.Visible:=false;  //area series' vertical lines

Hi Yeray,

Code: Select all

AreaSeries.AreaLinesPen.Visible := false;

Sorted it! Thanks a million.
