1. I want to know how to add "null" value to a Bar.
Please refer to the attchment, which is waht i want.
There is an empty value among a value list.e.g.,[2,4,3, ,44,55]
How can i create a bar based on this value list?
In TeeChart, I try the following code, but it fails..
Bar series = new bar(tChart2.getChart());
series.add(2);
series.add(4);
series.add(3);
series.add(null); //this is impossible
series.add(44);
series.add(55);
2. by the teechart example,
I know that i can use the following code to do this:
series.setNull(3);//index 3
Are there any other method to do this task?
What's more, in the example: "Chart Styles/ Standard /Line(Strip)/ Line/Horizontal line TreatNulls"
When i choose "Don't paint", the 12th is not painted, but the 13th still is painted.
I think both of them should not be painted.
Thanks

Re: Null value bug
I want to add null to a bar.
The TeeChart example is about line.
So i use bar.addNull().
there are several null values, so i use
bar.add(3); bar.addNull(). bar.add(4), then bar.addNull()
IndexoutofBoundsExpection Error happens.

Re: Null value bug
Because the above approach fails.
So i search this forum to find more useful information.
I find http://www.teechart.net/support/viewtop ... ull#p56858
which contain the following code:
I try the code, but my result is different , all the bars are painted even setNull().
I am using the latest version.
Could you please try it in the latest version..
Thanks.

Re: Null value bug
Hi,
It's a known bug already int he wish list to be fixed for future releases (TJ71016752). We'll try to fix it for the upcoming releases.
I'm afraid I can't think on a workaround at the moment.

Re: Null value bug
Hello, I try the new version TeeChart Java v3.2013.1219 version.
I find a problem, it as follows.
if i use bar.add(-10), it will result that Null will be showed. (Null-2.png)
however, if i use bar.add(10), it will result that Null will not be showed. (Null-1.png)
I think in both cases the null should not be showed.
Thanks.

Feel free to add your mail to the CC so you'll receive an notice when the status of the ticket will change.
If I scroll down the chart, I also see the null value drawn when bar.add(10) is being used. It's just that it's so thin that it's not visible with the default axis scale.rubby wrote:if i use bar.add(-10), it will result that Null will be showed. (Null-2.png)
