Can I reduce the number of vertical grid lines on chart?

IanMcCarthy · Post by **IanMcCarthy** » Thu Dec 07, 2006 6:45 am

The chart on my databand can display anything from two or three points to several hundred.
The vertical grid lines seem to be drawn for every data point displayed (likewise with major ticks).

The x-axis labels get drawn at regular intervals where space permits.

Is there a way to only have the grid line (tick) drawn if a label is displayed?

Charts with several hundred data points have five or six labels across the x-axis, hundreds of ticks (looks like a millipede) and the chart data area has a hatch
pattern from all the grid lines.

One grid line (tick) for each visible label would be clearer, can this be done?

Please use the Step property of the Chart component.

Thank you.

What that does is change the number of data points (and hence grid lines and ticks) between each displayed x-axis label.
If I have 100 data points and set step to 10, then I still see 100 grid lines (and ticks) but only 10 x-labels (one every 10 data points).

What I would like to see is one one grid line, one tick and one label every 10 data points.

So with Step = 0, display grid line and tick for each point with visible label.

Changing the setting for Step doesn't change the number of grid lines or ticks displayed, only labels.

Downloaded latest dll pack and I am able to match the number of ticks and grid lines to the labels, many thanks.

However...

I now notice that the vertical axis draws extra tick marks from the bottom of the chart area, down to the edge of the chart object.

No labels, just ticks.

I didn't get these before.

I'm not setting any step for the vertical axis, it's the default zero value.

Are you getting the same?
