At present, many programmers are basically using the back-end generation of data generated to the front end, and then the front of the data rendering to the drawing library above the display, so we finally see the various plans, but sometimes, we found that need to pass A lot of data, then this time if the data passed to the front analysis and display is very slow, so it is necessary in the back-end of the various charts generated, the following we come to talk about how the various programmers To make a picture
JqGraph and PHP's gold partner, with JqGraph we can complete a lot of map production, such as scatter, histogram, line chart, stock charts, pie charts, etc., and so on, And the current library has been supporting PHP7, so we can rest assured that use.
In the article, we have introduced the drawing software partner Bokeh on Python, which we can use to complete a lot of graphs. The basic graphs include histograms, line graphs, dashboards, scatterplots, Lorenz diagrams, two-dimensional three-dimensional flows Line chart and so on.
For Java programmers, the often used library is JFreeChart. With JFreeChart, we can implement pie charts, bar charts, scatter plots, time series, Gantt charts, etc., and can also be associated with excel and PDF, etc., will save the map to the local and so on.
For Andrews programmers, its classic old partner is MPAndroidChart, use it, to achieve a lot of plans, such as histograms, line charts, scatter charts, pie charts and so on.
