Turn off mouse click crosshair
In my application I have a domain crosshair that is set and moved as the mouse is moved. It works great. I also have it so I can "freeze" the crosshair by clicking the mouse. Then when I click the mouse again the crosshair will start moving again with the mouse movement. The problem is when I do the...

Re: Quadratic and higher-order regressions
If you wrote your own code you are covered. Many large companies including IBM have lost lawsuites against some guy who wrote his own programs that duplicated capabilities of their applications. It's the code itself that is protected by copyright laws. Not the idea. The idea would have to be patente...

Angles between lines
Things are going great with the charts development. But I have run into a new challenge. I need to calculate the angle of divergence between two lines. I automatically assumed this would be easy. The two lines represent the hypotenuse of two right angle triangles. Simple trig. Not so fast!! The angl...

Problem with SegmentedTimeline on 1.0.13
I just upgraded to version 1.0.13. Now SegmentedTimeline no longer works. I just use a simple statement in my code. DateAxis timeAxis = new DateAxis("Date"); timeAxis.setTimeline(SegmentedTimeline.newMondayThroughFridayTimeline()); The chart never gets displayed. I have tried tracing execution on Ec...

Re: Determining axis values at a mouse poisition
That helped a lot. I am now able to get the value of the x and y axis. Thank you very much!!!
One more question. Is it possible to also get the index of the domain axis instead of the actual value?

Determining axis values at a mouse poisition
I am trying to come up with the code to take the location of a mouse pointer and determine the value of the domain and value axis that cooresponds to that location. I set up a ChartMouseListener on the ChartPanel and can pick up the X and Y coordinates from the MouseEvent trigger in the chartMouseMo...

Missing ticks for montly
I have my OHLC chart working pretty good now. But I have run into a bit of a problem. It was an interesting challenge to get the segmented timeline to include only the days that the market is open. But I did make that happen. But this has introduced a problem. When the chart goes out to 12+ months i...

Re: Overlaying HighLow chart with scatter chart
WOW!! Thank you !!! That worked wonderfully. Everything is lining up perfectly now. I am beginning to think I might actually be able to manage what I need to do here! Now I have another questions. Is it possible to use a gif or jpg file as the image to use for the scatter plot? I am using the scatte...

So on the data consists of zero values and then non-zero values where I want a bar identified. What I am getting is wierd. Instead of the scatter chart symbol...

Re: Moving Average algorithm, problem or not?
I think you can use the createPointMovingAverage() method to calculate the average the same way your project manager wants it. I don't know which is the standard way, but then technical analysis of stock prices is not really a science, so it probably doesn't matter a whole lot. Actually it could ma...

Re: itemlabel for HighLowChart (and image labels)
Hey dmitryx, what you have done may work for something I am trying to accomplish. I need to place text and/or symbols at specific spots on a chart. Please post your code.
Is it possible to, instead of text, have it pick up an image file (gif, jpg, etc) and place it where the text would go?
