My chart lineDataSet entry maybe has more than seven, but the xAxis Labels only have seven at most. I have setting: xAxis.setLabelCount(7, true)，force is true.
The X-axis label type is Date, corresponding to the Y-axis data. Although the labels are evenly divided on the X-axis, they cannot be aligned with the Y-axis data. Unless force is not set, my requirement is that the X-axis only displays up to 7 dates.
Is there a way to ensure that labels can be aligned when multiple data is based on demand (see screenshot). LineDateSet has nine entries. How can I align the X-axis labels?

I want to show values as pixels. But my x-axis and y-axis show different range.I don't know what these values are telling us. But I read somewhere that we have to read the values as intensity values. They will not be visualized on the axis. Then what these axis are telling us? Secondly if I use xticks and yticks to label x and y axis does it has any effect on the image? Does it flip anything in the image?
`# a is an array of shape(500,2)
plt.xticks(np.arange(0,2))
plt.yticks(np.arange(0,500))
plt.imshow(a,aspect='auto',cmap=plt.cm.gray)`
I make a plot with different subplots (using gridspec.GridSpec). Two subplots share the same x-axis (sharex=ax1 in the definition of the second subplot).
However, as one subplot shows the indices of the chronologically sorted data, and the second subplot shows the corresponding decades, I want seperate ticks and labels for the x-axes of both plots. This seems not possible, a unique set of labels and ticks are assigned to both subplots. Until now, I can only:
use different x-axes and thus assign two sets of ticks and labels.
In that case, the axes are not alligned although
ax1.set_xlim([start, stop]) are similarly defined for both subplots
use a common x-axis and one set of ticks and labels
I do not find a solution for this on the internet. Is someone able to help? Thank you in advance!
I'm making plots where the (0,0) position is not necessarily in the bottom left corner of the plot frame, meaning that the x and y axes and their ticks cross within the plot frame. It's fine to have the lines, ticks and their values within the frame, but having the axis titles so near to their lines interferes with visualization of certain data points.
I'd simply like to force the x and y axis titles to be at the bottom and far left of the plot frame, respectively; it doesn't work to simply 'pad' the xlabel or ylabel titles because the padding I'd need would vary between plots.
How to get the titles always in these consistent locations of the plot frame, even if the corresponding axis lines, ticks/values may vary in the plot frame space?
Thank you.
I'd like to add a note here. It seemed to me that it could be possible to define the xlabel and ylabel 'labelpad' values directly from the data range:
For example, one could find the minimum x-value of the minimum y-value (this would set the position of the x-axis label), and the minimum x-value of the minimum x-value (this would set the position of the y-axis label):
xpad = ax.get_ylim()[0]
ypad = ax.get_xlim()[0]
Then use these values in xlabel and ylabel parameters as labelpads:
pylab.xlabel("X Title", fontsize=12, labelpad=abs(xpad))
pylab.ylabel("Y Title", fontsize=12, labelpad=abs(ypad))
Unfortunately, it doesn't look like labelpad can accept variables. Any suggestions that might allow a work-around?
I have a lineplot with 2 lines on it...they're two separate channels from the same data set. Would love to just label each one - the "labels" options are all about giving a number for each point on your plot, and that is simply not helpful.
Would love to know how to do any (really, all, but I just need to do one to be happy) of these:
plot each against its own y axis and be able to sensibly label that axis with units (and color the numbers to correspond to the data it correlates to)
put a legend on it. I can't figure out how to use lineLegend
just put any kind of (singular) label in the vicinity of the lines.
I want to make 21 subplots using the matplotlib. In some of the plots, fonts of axis are overlapping on the X-axis but X-axis labels are OK. For example, X-axis of one plot has value of (0,10,2) and adjoining plot has value of (0.001,0.010,0.002) so in subplots, 10 (on first X-axis) is overlap with 0.001 (X-axis of adjoining plot). If any one know about it then please reply me.
Many thanks

A few things you can try:
Adjust subplots so that there is more wspace and hspace
Adjust xlim/ylim manually to make sure there's no overlap (tricky)
Use tight_layout (see this question)
