  OHLC Financechart too dense a grid with long term annual data

I'm putting together some charts using the FinanceChart library under PHP.  This example was created with addHLOC() and addVolIndicator() on a FinanceChart() object.

I've got some data sets that go back a lot of years, with one point per year.

My problem is the grid for annual data - it just ends up with too dense a grid, since it draws one vertical line per year.

Is there any easy way to change this, for example to one per 5 years or 10 years?

Thanks,
Doug.

Hi Doug,

You may use FinanceChart.setPlotAreaStyle to set the minor grid lines to transparent. For example:

$c->setPlotAreaStyle(0xffffff, 0xdddddd, 0xdddddd, Transparent, Transparent);

Hope this can help.

Regards
Peter Kwan

Peter,
Thank you - that seems to have done the trick.

I do appreciate the richness of ChartDirector, but it can be tricky to find the correct option, especially when you're just learning it.

Thanks again.

Doug.
