Export image

Hi, Is it possible to export a chart image without displaying the chart on the device first? I am trying to write a class which does this so that the chart graphic can be saved and displayed in a document later on. But I don't seem to have access to tchart.getExport().getImage().getPNG() Thanks, Dave

Re: Legend checkbox styling

No worries.

I'll just try with various shades of grey to white in the legend to get the best look for now.

Any hints to the next release date?

Thanks

Legend checkbox styling

Is there a way to style the checkboxes in the Legend?

If I have a black background, you can see the outline of the checkboxes, but not whether they are ticked.

Re: Axis color

Before buying TeeChart, I was using aChartEngine, and you could add a transparent shading below each series line, as in the image below.

Re: Axis color

Now I'm not sure that Area is what I want. Is there a way to shade below the lines of a line chart?

Re: Axis color

Thanks Yeray, It looks like I've set up my Area chart incorrectly: Series ln = new Area(tchart.getChart()); ((Area)ln).getAreaLines().setVisible(false); ((CustomPoint)ln).setStacked(CustomStack.NONE); [do a loop here] DateTime dt = new DateTime(blah,blah,blah); ln.add(dt, double(DurationData.get(i)....

Re: Axis color

Thanks, Yeray.

Is there a way to remove the black lines from the area chart, and how can I change the look of the background grid?

Thanks

Re: Change Legend Font Size

Yep, my bad. I'd actually come up with a more long-winded approach, but yours looks better! DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); switch(metrics.densityDpi){ case DisplayMetrics.DENSITY_LOW: chart.getLegend().getFont().setSize(10);...

Re: HighLow chart with TimeSeries

Thanks Yeray, My intial downfall was choosing the wrong Add method, as you pointed out. I've changed the db and my PHL class to provide the max and min values for a given date for a given 'thing'; where if there is only 1 entry, max and min are the same. This is the code now: chart.removeAllSeries()...

Re: Change Legend Font Size

Thanks Yeray, I tried your setsize(20) answer and, although it made the xhdpi legend text more readable, it also scaled up every other dpi, which made the screen look stupid. Images are below... I would say that this issue should be removed from the 'wish list' and added to 'urgent action', as this ...

Re: Change Legend Font Size

Having said that;

The above example is using Galaxy S3 as a test device, which is XHDPI

The below image is from a test using Galaxy Ace, which is MDPI, and that looks fine. Could it be to do with how TeeChart renders XHDPI?

Change Legend Font Size

Is there a way to change the font size of the Legend? In testing (with Galaxy S3), I have a Pie chart with 18 entries. The Legend is hard to read as the text is too small. I thought I would change the data and group everything below 5% into an 'Other' entry, which left me with 14 entries. I expected...

Re: HighLow chart with TimeSeries

Thanks Yeray, I've reduced the data within PHL for this testing as it included what I would consider to be multiple series. This is the data which is being sent via hl.add(dt, (double)PHL.get(i).getSeverity(), PHL.get(i).getName()); 10/11/12 8 Buttock, Right 10/11/12 7 Buttock, Right 11/4/12 8 Butto...
