Update Chart

[bassam]

Hi,
I'm developing an indicator that calculates the price difference between the start
and the end of a line user drew.

But to get the text with value plotted on the chart I have to press F5 every time I change
the position of the start or the end of that line.

So how to update the indicator from within Ninjascript?

Hello bassam,

Thanks for your post.

While this is not supported, after these calls try:

ChartControl.Refresh();

Let me know if this is not what you are looking for.

Thanks Chelsea,
That did not work, I tried to call it from :

public void MyMouseUpEvent(object sender, MouseEventArgs e)
{
Print( "Click works");
ChartControl.Refresh();
}

"Click works" gets printed in the OutPut everytime I click the chart, but the chart does not refresh.

Hi bassam,

I overlooked the part where you mention that this is a user drawn line.

Currently in NinjaScript you cannot change the end points of manually drawn objects.

While you can find the object and print all of the details of the object, a manually drawn object cannot become dynamic.

This is somewhat mentioned in the following thread.

Dear Chelsea,
I'm not trying to move the end of a line were drawn by the user.

I'm trying to refresh the chart as if you pressed F5.
Suppose you have a control button, what I need is the procedure or function that reload the chart
again once I click it.
