Is there a way to limit the fill area for Area charts and Bar charts to the lower limit of the chart?

If my lower range is positive 50, I don't want the fill covering the area below the chart.

tks

Hi James, 

If I have understood you correctly, you can achieve this by setting the "UseOrigin" property to false.  

By doing that, the area will begin at the minimum area value instead of the specified origin value. 

If this is not what you are looking for, can you give us more details on what you are trying to achieve? maybe an application or a screenshot that demonstrate your problem.  

Almost there!

I am setting the UseOrigin value and it eventually gets there.

I collect live data at 10 times per second. I manually set the origin to the lower chart limit, but the fill area stays below the chart until all data less than my lower limit has cleared the queue. Then my origin appears to be the lower chart limit.

It seems like if I manually set the origin, the fill area should start where I tell it to. Or am I not setting to correct property?

How do I start the fill area at my lower chart limit regardless of any data point in the queue?

tks.

Hi James, 

Can you send us a sample application that reproduces the problem so that we investigate this in more detail?

You can send it to support@xceed.com ,  please include a reference to this forum post in your email.  

Found it...

I need to leave the UseOrigin set to true. Just set the origin to the value of my lower chart limit.

Now all my data below the chart gets the fill.

I just need to "correct" all my data points in the queue so nothing is less than my lower limit.

tks.

Now I need to to something similar to a bar chart with multiple bars.

I only want the fill effect to draw from the lowest data point to the highest data point, not all the way down to the chart lower limit.

Hi James, 

It would be the same for the Bar chart.

You only need to set UseOrigin to false for it to only draw the lowest to highest data points.

You can see it in action by checking the chart sample application; Check the Standard 2D Bar sample under  All Examples / Chart Types / Bar in the treeview. uncheck "Use Origin"
