Graph gauge and math syntax

General Feature requests
1

I have some general questions and maybe suggestions for using realdash

  1. Can I somehow set up a grid for the graph gauge ? To draw vertical/horizontal lines on the chart for each of the axes. If not, is it possible to add such functionality in future releases? It would be very convenient when debugging various systems, I think many engineers will agree with me.
  2. Is there any guide on how to use gauge math ? With a description of the entire syntax and possible functions. Is it possible to use multiple variables for math or add such functionality in future releases? for example: v = ecu_var1 * ecu_var2 * 0.5

  1. Sure, sounds like a good idea. Will put to the feature request list.

  2. Currently just some tidbits here and there. I will make a note to write something to the forum FAQ.

Re Gauge Math, is it possible to use other values in the calculation, and reference them by their name?

For example, I have a custom tag in my xml, let call it ecu: wheel direction can I use this in the Gauge math like this? =V*”ecu: wheel direction”

Yes, if value is built-in value, use its ID like this:

=V*ID37

Would be gauge value of original value * RPM. See list of ID:s here:

RealDash | Manuals | Target Identifiers

You can also refer to custom values with single quotas (')

=V * 'My Custom Value'
