I have a simple line graph that shows daily pricing for 3 months. I need another Y-axis on the right to be label as the same scale on the left. How can it be done?
I'm now using secondary axis to do this which will have 2 lines overlapping together which is ok as it does not affect my graph. However it shows an extra element for that secondary axis in the legend. How can it be removed?
Please help. Thank you.
You can install the customizer and go to chart properties in order to see if you can use second Y axis labelling or not.

I have a control chart, with on the X-axis a time period, and the Y-axis the value of the measure (I'd like to plot all the points in a control chart).
However, I have 2 different values as a measure, which have the exact same date (up to a second match) but different measure values.
When I plot this on a control chart, instead of having 2 points in the control chart with value 500 and 550 for example - it gives me one point with a value of about 200.
It also gives a notification that there is a NULL value in this axis, which points to the X-axis where 2 records have the exact same date.
Any idea what I can do to make this correct - or make tableau draw the measure points correctly?
Thanks in advance!
It's difficult to answer without seeing more detail about your problem, but this sounds like a good candidate for a blended axis. (multiple measures sharing a single axis)
The easiest way to do this is to put your (probably continuous) datetime field on the row axis and one of your measures on the row axis to see one of then control plots. Then drag the second measure to the Y-axis until you see a little translucent two bar icon to indicate that you are adding a second measure to that axis, at which point you can release the pointer and you should see a two plots on the same axis.
If the scales for the two measures are radically different, you can instead drag the second measure to the right side instead to get a dual axis.
Just want to find out if anyone have encountered this problem before.
Basically I am currently using Flot version 0.8. I am trying to plot a chart with multiple yaxis against datetime in xaxis.
The Left yaxis are for values which normally range between 10-80 whereas right yaxis are for values range between 100-500.
Is that even possible to have them plotted with the same tick size (E.g., 20) and the dimension of the chart is fixed.
At the moment, FLOT will automatically apply different tick size on left and right yaxis.
What do you guys think?
Use the tickSize option to set the same interval on both axes. See the customizing the axes section of the docs for more info.
The MATLAB surf plot below is essentially two plots plotted adjacent to each other. For clarity, I have included some code below used to prepare the plot:
band1 = horzcat(band1, eSurface2(:,:,1));
band2 = horzcat(band2, eSurface2(:,:,2));
surf(band2,'DisplayName','band2');
surf(band3,'DisplayName','band2');
I would like for the y axis numbering to restart at the start of the second graph. How do I go about doing that?
You can use the 'YTick' and 'YTickLabel' properties of the axis to control the ticks, this way you can make it start from zero for the second graph. It will require some trail and error to get it right. See the relevant doc here (you'll have to scroll all the way to the bottom of the page).
Take advantage of the following feature of 'YTickLabel': "If you do not specify enough text labels for all the tick marks, MATLAB uses all of the labels specified, then reuses the specified labels".
I have the tick label set for the x-axis already and I also have the label set for the x-axis too. I am seeking a way to put an additional x label to the rightmost of the figure next to the x tick labels, is there any way to do so? Thanks
just like the following figure, the x ticks was added automatically and x label was added by the command xlabel. But I want to add one additional label "add'l" (red) in the figure. But I have many plots and/or subplots and the axes might be different, so I need to add that label with problem instead of manually.
I suggest using a uicontrol that will be carefully placed in the relevant area.
uicontrol('style','text',....);
If your UI is resizable, be sure to have the same units, i.e. if the text units are Normalized, then the axes units should be Normalized as well.
Check out this example on the MATPLOTLIB gallery page: http://matplotlib.org/examples/pylab_examples/alignment_test.html
It shows adding all kinds of different text to the axis.
If I zoom several time graph all labels from axis X disapear (go away) and there are no visible axis X labels so it is not possible to understand the part of graph where am I.
How can I force matlab to always display labels on axis X and to update them automatically while zooming and to display enough digits so "neighboor" labels must be different.
it depends, are you manually setting the tick marks yourself ('XTick' and 'XTickLabel' axis properties)?
Try this simple example
plot(sin(1:10), 'o-')
without changing anything, you can zoom as much as you want, and the tick labels will always be visible
EDIT
The root cause of the problem is the same as the one raised in your other question, datetick function will manually set the tick labels, thus disabling automatic update on zoom/pan.
The good news is there are already submissions on FEX that tries to solve this exact problem with DATETICK
I run into the same problem even on the new version of MATLAB (r2014). MATLAB does not display sufficient x-axis tick labels as you zoom-in. After several experiments I found the following workaround. Following is a plot before implementing the solution. MATLAB displays only three XTick labels on the x-axis even though there is sufficient space for more (there are often even less labels as you zoom in more).
Suspecting that MATLAB thinks that it does not have sufficient space to display more labels, a workaround can be to rotate the labels. To do that, after you issue the plot commands, e.g.
plot(tsX);
hold on;
plot(tsY);
plot(tsZ);
add the following command
set(gca,'XTickLabelRotation',90);
Now MATLAB plots with more labels
I am going to report this as a bug to the MATLAB guys.
