I know this is a bit of an old topic but I have a question about the arrow endcaps that can be placed on the lines drawn with the DrawLine tool. When I use the code you demonstrated, the arrow does appear on the end of the line but it's really small. Is there any way to control the size of the endca...

Hi Aaron, Thanks for the example project. After checking its implementation I think I have found the cause for this problem. When you loop through your series for setting null points (as in code snippet below) you are incrementing the loop variable twice at each iteration: one in the for loop and t...

Like I said in the email response I made, looping through the data is NOT how we determine what is assigned as NULL. This was done as a simple example and a way to put Null values into the series to show something similar to what we end up with after we filter our data and place the Nulls in where t...

I just sent it.
I attached it to a separate email since the first one had the project stripped off due to the size being too large for the Siemens Exhange Admin settings.
The project zip file was only 1MB or so and appears to have gone through from my side fine.

I have a sample app I will be emailing to the support address. I will include in the email a link to this thread. The problem seems to be with TreatNulls and the way we previously used the IgnoreNulls property. When points are VERY close together, it seems that a NULL value is causing a good value t...

I am doing a lot of investigation into this issue since our users have a lot of problem with the fact that there is data missing from our graphs. It appears to be related to the TREATNULLS property. The old version that we used to use was back when Series had the IGNORENULLS property and we set it t...

Hi Aaron, The problem probably is that your color line tool needs to have associated a series that uses a custom axis because, by default, it uses the Left and Bottom axis so, if you don't have one of them, the tool can't use it. This does appear to be the case. Any chance we could add that to the ...

Yes. But with that I meant that your DrawLines will behave as you reported until you populate your series so that axes scales are set or you manually set their scales. But my series is already populated and drawn on the graph using one of my custom vertical axis BEFORE I am trying to draw a line on...

So if my custom vert axes are set to Automatic = true and I add series to the graph with one of those custom vertical axes as its vert axis, then the Min and Max for that custom axis should be set automatically by TeeChart? I will have to double check to see what is happening then. Because I only us...

In that case this is most likely because your axes didn't have any range set. Probably setting axes minimum and maximum (for example using SetMinMax method) would also make this work. My axes are using the .Automatic setting of TRUE to allow TeeChart to determine what should be displayed based on t...

Ok, I have made a little progress. If I have a data series on the graph that is plotted onto any of my cumstom vertical axes, I can assign that series to the .SERIES property of the DrawLine tool. That will allow the vertical component of the lines drawn to appear to work properly. Is there an edito...

I have an application that uses TeeChart .NET v 3.5.3371.26406 I have the LEFT and RIGHT axes visibility turned off. I have 6 customer vertical axes. When I try to add a DrawLine tool to this graph, I can draw lines but only horizontal lines. I cannot control the vertical location of the lines unles...

We operate on a standardized platform on only the company maintained machines. The results we are seeing are 100% reproducable on multiple machines with the versions noted. Most likely, I will try to update the the very latest service release and see if we continue to see the same issues. If we do, ...

We have been using the .NET versions of TeeChart for a few years now. With a recent version of our application that we released we are seeing a significant difference in the points that are visible when a graph is drawn to the screen in our application. The data is all present in the Series objects ...

We had some confusion here regarding your polynomial fitting function and the degree parameter that is passed to that function. The degree is limited to be between 2 and 20. When we pass degree 2, we get a linear polynomial (a line, y=mx+b). But that is defined as a Degree 1 normally. And degree 2 u...
