I’m having my usual fun with charts. Working on mycheckpoint, I’ve generated monitoring charts using the Google Chars API. But I’ve also had chance to experiment and deploy interactive charts, JavaScript based. In particular, I used and tweaked dygraphs. I’d like to note some differences in using charts of both kinds. And I think it [...]

By the end of this post I’ll present some real-data charts, area charts and colored charts. +———+———————————————————————————–+ | y_scale | chart | +———+———————————————————————————–+ | 1 | ****———#######—————————————-*******——–###### | | [...]
My other half says I’m losing it. But I think that as an enthusiast kernel developer she doesn’t have the right to criticize people. (“I like user space better!” – she exclaims upon reading this). Shown below is a (single query) SQL-generated pie chart. I will walk through the steps towards making this happen, and [...]
I wasn’t sure I was to go this far. After catching breath the following have been added to Generic, auto scaling, scaled SQL graphs, and these will conclude my current hacks: Displaying X-axis min/max values. Support for Y-axis values precision. Support for pre-defined scale range. The addition of the above makes for presentable, usable graphs. [...]
In Rotating SQL graphs horizontally, I have shown how to rotate an ASCII SQL graph into horizontal position. I was dissatisfied with some parts of the solution, which I will show now how to fix: I had to manually scale the graph values so as to fit nicely into screen. I had to rely on [...]
