Hello Nasir,

Thank you for your post. I have been looking into and I created a sample project for you with the functionality you want. Also I can say that for the ScatterLineSeries yo uneed two numeric Axes.

Hope this helps you.

Stephen,

That's exactly I am expecting. But data points are not aligned. Please run this sample.

See the result. First FillDataPoint is plotting at 1:15:00 (YAxis value = 115) instead of 2:15:00. And last FillDataPoint is plotted at 2:45:00 ((YAxis value = 115) instead of 4:45:00. There are 5 data points for both Fill and Tick at same time (2:15:00, 3:15:00, 3:45:00, 4:15:00 and 4:45:00) but they are plotting on different time.

Please run this program and let me know how to fix this.

Thanks

Hello Nasir,

I have created a sample project for you, using the code you have provided, with the functionality you want. Basically I used CategoryDateTimeXAxis instead of CategoryXAxis and I set its MinimumValue and MaximumValue Properties, so now the Datapoints are aligned.

Hope this helps you.

Hi Stefan,

Thanks for your help. I can see expected result in the sample.

But in my application when I tried to use CategoryDateTimeXAxis instead of CategoryXAxis it is taking very long (or application hung) to plot the points. I have more than 30,000 TickDataPoint and around 200 FillDataPoint.

And if I change back to CategoryXAxis it works fine but Datapoints aren't aligned as before.

You can change your previous sample to generate more than 30,00 TickData points and 200 FillData Points and check the result.

Let me know what can be the issue here.

Thanks

Hello Nasir

To achieve the functionality you want, you have to use CategiryDateTimeXAxis, because the spaces between data points, based on the amount of time span between them, are important and since CategiryDateTimeXAxis perform sorts on the data it is expected the it takes more time to load than the CategoryXAxis. Also I can say that both Axis should have the same Minimum and Maximum Values equal to the Minimum and Maximum Date of the TickDataPoint collection.

Hope this helps you.

Hi Stefen,

Thanks for your help. I got the point. I will do work around to reduce the time.

I have other question related to same application.

How can I change/format the color for FinancialSeries. I want Candle Stick to be red or blue. I also want to change the color of point in PointSeries based on value.

Please let me know and if its possible give me sample code.

Thanks

Nasir

Hello Nasir,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well.

Thanks again.

Stefen,

Thanks for your help.

Nasir

Hello Nasir,

I have modified the sample, so now it has the functionality you want. Basically I set FinancialPriceSeries' NegativeBrush in order to make the Series Red. Also I create a MarkerTempalte for the PointSeries and used a Converter to set the color based on the value.

Hope this helps you.
