![]() I would say a DPI+space API option would be much more useful and valuable only if things like line width can be made to consider DPI. You would currently need to take that into account manually and bump line width yourself on large output sizes if you want that. If your line width is “1” then it is 1 pixel whether the output image is 300 pixels wide or 30000 pixels wide. What is tricky is that things like line width are specified in pixels which mean that can’t take the DPI into account. You have to compute that manually for now. Either way, in general you can only ever control two of those things, and Bokeh also demands that (# pixels) be one of them.Īgain, it sounds like you want a different API that let’s you specify DPI and space, and computes the image pixel size automatically. Or if you are using software that will respect the reported DPI in the file, and adjust the rendered output size accordingly (taking the size out of your hands). It’s up to you to decide if you want to fix the output size when you display the image (thereby mathematically determining the DPI-whatever is reported in the file is made irrelevant). These are related by: (# pixels) * DPI = (# inches)īokeh fixes the (# pixels). And more importantly, you can set the DPI value in the image file to anything you want. But anything and anyone is free to ignore the DPI value. In general, the only effect the DPI value in the file has is to tell other software (that cares to look), how much physical space those pixels should take up. If you ask Bokeh for 300x300 output, you will get an image with 300x300 pixels. It’s definitely pixels, and the number of pixels simply is what it is. If you are just asking for a way to override the reported DPI in the image, then that’s probably a simple thing to do and I don’t see why it couldn’t be done as long as the documentation was extremely clear that setting the value is you stipulating a DPI. I don’t think there is any value in that, until or unless there is also a way to specify things like line widths in DPI-aware units, but that would be a non-trivial task. ![]() It sounds like what you are are asking for is an API that takes a DPI and a target image size in physical units, and automatically generates an image of an appropriate pixel size based on those given physical dimensions? There is no API in Bokeh that will do that. The DPI field in the image is mostly irrelevant, since nothing at all can stop you from rendering a 300x300 pixel, “300 DPI” image in ten inches of screen space, making that DPI value completely false. There are no 3D graphing features available.DPI is a function of the pixel resolution (size) and the actual physical dimensions that you render that image of that size into. ![]() It is compatible with IPython shells, Python scripts, and Jupyter notebooks. The dashboard is served using the Bokeh server. ![]() It is compatible with many programming languages. It is great for beginners but only Python can be used. Only Python programming language can be used. Matplotlib is a quick and straightforward tool for creating visualizations within Python. Makes it easier to modify and export your plot.īokeh is the ideal tool to build dashboards and charts quickly with interactivity. It is difficult to modify/export your plot. Styling graphs with bokeh is a tedious process. Plotting using Plotly requires only a few lines of code. It has various output options for the plotted graphs.Įach additional plot feature requires an additional required code line of code. The functionalities can be extended by using third-party packages. It has many interactive components like zoom, pan, search a coordinate, etc. Used to create interactive web-based visualizations and even web applications. It is capable of handling geographical, scientific, statistical, and financial data. It is one of the most simple ways to plot data in Python. Plots made with Bokeh are flexible, interactive, and shareable.
