kandi X-RAY | spectrographic Summary
Most sounds are intricate combinations of many acoustic waves each having different frequencies and intensities. A spectrogram is a way to represent sound by plotting time on the horizontal axis and the frequency spectrum on the vertical axis. Sort of like sheet music on steroids. What this tool does is, taking an image and simply interpreting it as a spectrogram. Therefore, by generating the corresponding sound, we have embedded our image in a spectrogram. The game DOOM used a similar technique to hide satanic figures inside its soundtrack. Now everyone can do the same! . Get the command-line tool spectrographic via pip by running pip install spectrographic. You can also simply use spectrographic.py from stand-alone\ as a command-line tool directly. Furthermore, make sure you meet all the dependencies inside the requirements.txt. Install them with pip install requirements.txt. After installation with pip one simply needs to run spectrographic [...] in the console and with the stand-alone script you have to use python spectrographic.py [...] inside the folder containing spectrographic.py. You could also simply import the SpectroGraphic class from spectrographic.base. Check the doc-strings for detailed explanations and more features.

QUESTION
I am using ggplot2 to plot some spectrographic data from a large list of data frames. I want to restrict the graph to just wavelengths between 400 and 900 nm. I know how to set the x-axis limits using scale_x_continuous() or xlim(). The problem is that after I have done this, the y-axis does not automatically readjust to the min/max values displayed. I don't want to set it manually, as each data frame processed by my loop will have a different range.
Where summary
is my list of data frames, then this code gives me a list of plots, without the axes adjusted:
ANSWER
Answered 2017-Feb-23 at 13:17Here is a possible solution. However, since I don't have access to your data, I wasn't able to test whether it actually works.
You could define the max average value for the range of wavelengths prior to building your plot and then call that value in a ylim function.
The two lines I added are:

Install spectrographic
You can use spectrographic like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
