FinancialCharts and FinancialChartsClass

[User (Legacy)]

In design time I added finanial chart to my chart so, what is the difference between saying

Dim fExt As CfxFE_COM.FinancialCharts

fExt = AxChartFX1.GetExtension("CfxFE.Financial")    then use fExt object in my code

 and saying

Dim fExt As CfxFE_COM.FinancialChartsClass = New CfxFE_COM.FinancialChartsClass()

AxChartFX1.AddExtension(fExt)  then use fExt Object

In other words, what is the difference bet'  FinancialCharts and FinancialChartsClass

FinancialChartsClass is the co-class. The class needed to CREATE a new instance.

FinancialCharts is the interface.

There is no practical difference, is just COM stuff.

Can u give me more information please 

for example, I created an object (fExt1) from  FinancialChartsClass and another object (fExt2) from FinancialCharts 

Then Why there is a difference in volume SHAPE when I say 

fExt1.Volume.Visibile = true   or say

fExt2.Volume.Visibile = true

No difference.

However, you can not do both.

If you already added the extension at design time, and then you do:

Dim fExt As CfxFE_COM.FinancialChartsClass = New CfxFE_COM.FinancialChartsClass()

AxChartFX1.AddExtension(fExt) 

You are adding TWO (2) Financial Extensions to the chart which is wrong.

So , either you add the extension at design time and then in your code retrive the pointer by calling GetExtension OR you do the code above. But you NEVER do both.

Actually I added finanial Extentions in design time and in runtime

I had to do that for my chart to works well, where I added one in design time then code using the other created in runtime

because If I used the extention created in design time only, no data appears in the chart

If I didn't add the extention in design time and use only that created in runtime, the chart is drown but in wrong values

So what is my mistake?

You CAN NOT add two financial extensions to one chart.

If you added the extension at design time YOU CAN NOT create another one.

If you added the extension at design time you must do:

fExt = AxChartFX1.GetExtension("CfxFE.Financial")

NEVER do:

 Dim fExt As CfxFE_COM.FinancialChartsClass = New CfxFE_COM.FinancialChartsClass()

AxChartFX1.AddExtension(fExt)

> because If I used the extention created in design time only, no data appears in the chart

What do you mean by this ? no data ? what shows in the chart ?

Bellow is my function that drows the online chart that drows only 2 values, volume and price

NOTE: I added the finanial extension at design time also (I got that this is wrong but I had to do that as I told u, so I ask to avoid this)

Hope u can help me

thanks
