I have a use case where i want to plot area charts along with bar/line charts. I am able to do that with no issues.
The problem I am now facing is the overlapping of colors when say, bar and area are plotted together. (Sample is below). In this, as you can see, the colors of the bar are getting overcast due to the area plotted.
Area + Bar + Line
What I would like to do is plot the area canvas as background and others as foreground. (PS: I tried by changing the sequence of plotting the series, which changes the sequence of canvas also, but the effect remains the same)
Is there a way to do that ?

I am using iOS Charts by Daniel Gindi.
I need to draw horizontal stacked area chart (Example). But I cannot find similar charts in examples of the library. I am trying to customise Horizontal Bar Chart like in example. But I cannot to avoid square corners.
How can I draw line instead of bars with squared corners?
Is it possible in this library or I should use another one?
Yes you can.
Use line chart instead ,and set drawFilledEnabled to true.
But the filled area is between line and x axis, so you may need to rotate the chart.
I've got a stacked bar chart with legends, but depending on the data selected, it becomes unreadable because of the space added around the bars and the series and the fact that the outer horizontal axis label won't rotate. I've tried as many things as I can think of, but nothing alters the spacing or the rotation on the outer axis. Picture 1 gives you an idea of what I mean. Main thing that would probably help is the rotation. Using VS2012 but not inline code. Any help appreciated.
I have a little mess with a GUI developed on Matlab. Basically, I have two axes, one to plot a bitmap I want to keep all the time and another one to do some ordinary plots. My problem is that when I try to do any plot on the second axes, the image on the first one disappears and the axis get restarted. I tried to plot over the image and it remains on the figure (only shifts because the axis change once the previous image is gone).
Any idea aout what is happening? By the way, it is for a chromatic tuner that plots a degradation from green to red depending on the accuracy and the FFT of the received signal.
1) Here is the code for the image plot:
colormap(cmap);
imagesc(bmp,'Parent',handles.axes_tuner);
hold(handles.axes_tuner,'on');
% Vertical line in front of the image
plot([L/2,L/2],[-length(bmp(:,1)),2*length(bmp(:,1))],'b','LineWidth',1.5);
axis(handles.axes_tuner,'off');
hold(handles.axes_tuner,'off');
2) Plot on the other axes
cla(handles.axes_fft);
hold(handles.axes_fft,'on');
plot(f,spectrum,'b-','Parent',handles.axes_fft);
xlabel(handles.axes_fft,'Frequency','FontSize',8);
axis([0 Fs -50 0]);
ylabel(handles.axes_fft,'Normalized Amplitude','FontSize',8);
hold(handles.axes_fft,'off');
I have an XY graph with a legend that automatically resizes to fit the contents of the legend. The problem is that sometimes the legend text is such that the resizing overlaps the plot, see the image below. Is there a way to keep the legend from resizing over the plot data? In other words to confine the resizing operation to outside of the plot box?
Update: it would seem that part of the problem is the auto expand ability of the legend always expands to the left-hand side. Placing the legend on the left-hand side of the plot keeps the legend from covering the graph.
1:
You probably have moved the legend, changing it's anchor point. You can move the legend to the right side of the graph element and it should re-anchor.
In Qlikview 11 I managed to set up (amongst others) a nice scatter chart without any major problems. Now I would like to be able to zoom into a region in that chart. Intuitively this could be accomplished by selecting a rectangular region with the mouse. Incidentally this works fine in "regular" line or bar charts. The new x and y axis regions correspond to the selected rectangle. However this does not happen with my scatter chart. I suspect this has something to do with the way dimensions are handled in scatter charts. For easier understanding I appended to screen-shots of the status quo - or how I don't want it to be.

From what it looks like, I would guess that the scatter plot has hard coded axis max and mins. Check the "Axes" tab under chart properties, and uncheck the scale boxes. That should allow the chart to zoom in.
