I use DBBrowser for SQLITE for charts. Is there another tool with more options?

I don't know of any tools, but will suggest crafting your own charts. This gives you complete control and all the options you could possibly need. I recently did this while experimenting with the SQLite shell tool compiled as WebAssembly. In these dynamic examples charts are output as SVG using only the shell tool (partially inspired by Richard Hipp's geopoly demo).

Oh wow, that's impressive!
One comment, this is eye-watering ;)
WITH x(x) AS(SELECT $min_x UNION ALL SELECT x+$sample_size FROM x WHERE x<$max_x) INSERT INTO x SELECT x FROM x;

Feedback acknowledged. Would this reduce the psychological harm?
SELECT $min_x+value*$sample_size x FROM generate_series(0, ($max_x-$min_x)/$sample_size);

Why all the complication. Why not just:
select value as x from generate_series where start == $min_x and stop == $max_x and step == $sample_size; or just select value as x from generate_series($min_x, $max_x, $sample_size);
you only need to do all those calculations if you are using wholenumber because wholenumber does not support setting the step size. ie:
SELECT $min_x+value*$sample_size AS x FROM wholenumber WHERE value BETWEEN 0 AND $max_x-$min_x)/$sample_size;

My first attempt at using
generate_series looked like this, but the official
generate_series implementation seems to only support integer parameters.

Yes, sorry, you are correct. Both generate_series and wholenumber only do integers, not reals.

I recently posted message [95898f0f51] to this forum with a extension to write PostScript output from SQL. Maybe you might find this useful if you want to make graphics with the SQL data.
