Symlog Ticks

Plot does a great job automatically producing an informative "context" around the chart, including great defaults for ticks and tick labels in a variety of situations. There are some areas where I reliably decide to modify the defaults, though, and one of them is with a symlog scale.

Here's a demo of the current default ticks for a chart with a symlog y axis:

For comparison, I think the default axis settings for a log scale are more informative, and include ticks that show values along the full value range:

Start with the linked demo and compare the current symlog y-axis ticks with the log-scale example shown in the issue. Trace how the chart chooses default ticks for symlog scales. Done means the symlog axis shows informative ticks across the full value range, comparable to the log-scale defaults.
