  Problem with Dash Line

Hello,

First of all thank you for developing this incredible library.

I have been experimenting with FinanceChart library and I ran into some problems trying to
create dash lines. I tried to create a FinanceChart object and make the background black
and the grid dotted lines. So I tried:

FinanceChart *c = new FinanceChart(window_width);
int dash_line = c->dashLineColor(0xdddddd);
c->setPlotAreaStyle(0x000000, dash_line, dash_line, -1, -1);

However when I run the program, the background color is fine but the grid lines are not
drawn. I just wonder what have I done wrong here?

Thank you again.

Ivan

Hi Ivan,

There is a limitation in FinanceChart that you cannot use FinanceChart.setPlotAreaStyle for any color defined using the FinanceChart object. Such colors are valid only for the FinanceChart container (eg. if you add a border for the entire FinanceChart), but not for the XYCharts contained in it.

See the followings for the method to use to make dashed grid lines:

Hope this can help.
