Hi,

You can either set chart.xaxispos to center:

obj.Set('chart.xaxispos', 'center');

Or go through your data checking for values less than zero - and set them to zero.

I came across the same problem. And I don't want to use code like:
obj.Set('chart.xaxispos', 'center');

I used myLine.Set("chart.ymin", -10), hoped to get what I want.

It showed like what I imagined. But it still alert:
"You have negative values and the X axis is at the bottom."

Any other way?

Hi there,

The ymin value does not stipulate the lower value when the X axis is in the center - the values are simply mirrored.

Hi there,

Like jack yang on 12th March 2013, I need to draw a graph with a custom ymin value (with the chart.ymin setting) and I don't want to set the X axis in the center.

How to disable the alert : You have negative values and the X axis is at the bottom ?

Thanx,

You can set outofbounds to true.
