Adjust max colour stretch values in PSRA maps

[drotheram]

Some PSRA maps look like a 'sea of cream colour' it appears the max value of the colour stretch is too

Here are appropriate global max values for

Looks better, waiting on fixed PSRA tiles to before we can close

@phil-evans There was a mistake with some of these values

[anthonyfok]

I am experimenting with changing the "Max legend value" etc. inside WordPress, using only baseline maximum, as follows:

Average Annual Fatalities: /wp-admin/post.php?post=561&action=edit&lang=en

• CSD: Max legend value: 0.99 → 0.9026128279
• SAUID: Max legend value: 0.0032 → 0.0276407533 ← this seems to turn more areas into cream colour?

Annual Probability of Fatality: /wp-admin/post.php?post=562&action=edit&lang=en

• CSD: Custom Scale Values: 1: 0, 2: 0.000001, 3: 0.000002, 4: 0.000003, 5: 0.000004, 6: 0.000005, 7: 0.000006, 8: 0.000007
  → Max legend value: 0.0000071514
• SAUID: Custom Scale Values: 1: 0, 2: 0.0004, 3: 0.0008, 4: 0.0012, 5: 0.0016, 6: 0.002, 7: 0.0024, 8: 0.0028, 9: 0.0032
  → Max legend value: 0.0000146418

The very last change (max value for SAUID for Annual Probability of Fatality does make it look more colourful. Example for Victoria:

I probably should follow @phil-evans's Custom Scale Values to make the numbers in the bottom scale legend (?) look more even? What do you think @drotheram and @wkhchow?

[wkhchow]

I think the change looks good as you can now see the differences much more clearly. Does the bottom legend scale automatically change once you adjust the max values?

[anthonyfok]

Yes, the bottom legend scale changes automatically. And there are two ways to do it, one with "Max legend value" where the system assign 9 steps linearly; another with "Custom Scale Values" where the number of steps and their values can be customized. Thanks to @phil-evans for the design!
