 Minor Ticks in Grid |

Hello,
I want to have different colors of vertical grid lines on days and monthes.
How may I set ticks with labels as minor?
Or may I change colors of vertical grid lines for defined ticks?
Or may I draw grid separate from tick labels?

Hi Alexander,
From your screen shot, I assume you are using the FinanceChart object.
In ChartDirector, for label based x-axis, if a label starts with the "-" character, it means the label is a minor tick label. (The "-" character will not be displayed. It is only used to specify that the label is for a minor tick.)
For a FinanceChart, the x-axis labels are automatically generated based on the timestamps. The date/time format is configurable using FinanceChart.setDateLabelFormat. See:
http://www.advsofteng.com/doc/cdnet.htm#FinanceChart.setDateLabelFormat.htm
You can change the format to include a "-" character in the format string, and it will become a minor tick. For the label in your screen shot, it is the "otherDayFormat" format, so the code is like (in C#/Java):
myFinanceChart.setDateLabelFormat(null, null, null, null, "-{value|d}", null, null);
You can set the minor and major tick grid line colors using FinanceChart.setPlotAreaStyle. See:
http://www.advsofteng.com/doc/cdnet.htm#FinanceChart.setPlotAreaStyle.htm
For example:
myFinanceChart.setPlotAreaStyle(Chart.Transparent, 0xaaaaaa, 0xaaaaaa, cd.Transparent, &Heeeeee);
Note that the FinanceChart.setDateLabelFormat should be called before your set the data to the FinanceChart. For example, you may call this method immediately after creating the FinanceChart object.
