PostForum: Getting Started   Posted: Wed Jul 18, 2018 6:36 pm   Subject: Fixed Range Values when Animating Plot
There must be a point that is repeated at the end. But there is a way to work around that. One of the options in the plot command is the Connect menu where you can pick "If x increases" so ...

The issue here is that the mask requires an exact match, so really the "time" variable should be an integer. If your time values are discrete, with initial time t0 and time step dt (for exa ...

PostForum: Getting Started   Posted: Sat May 19, 2018 11:13 am   Subject: 4.4-beta: Box plot "fill with color scheme", based
The color is based on the location or category label of the box (position).

The issue is that if you have say 1000 values and 10 bins, there are only 10 colors. But it makes sense to think about o ...

The "Number from Text Column" column can parse a specific portion. But there wasn't an option to understand binary/hex/octal numbers.

I added this and uploaded a new beta. You should ge ...

In the axis settings (3rd block) you can switch the axis between linear, logarithmic, reverse linear and reverse logarithmic.

The range will still be min,max for all four cases.

You mean the Color Scheme in the global variables?

Some drawing commands, such as Points, Range, Lines allow you to color discrete values based on the color scheme or color ramp.

One way to get this effect is by using the Scalar Field command in the beta. It's a little bit of a workaround, since the Scalar Field command is intended to draw a field of values coming from the da ...

You can define color ramp variable (not color scheme) and use that to color the points. There is also a color ramp legend command. This is new in 4.3, but was in the beta before that.

PostForum: Getting Started   Posted: Sat Mar 24, 2018 11:24 am   Subject: Double exponential decay curve
The issue might be that the range is too large for the standard least squares fit. In DataGraph, this is fixed by allowing you to fit it logarithmically, but in DataTank this option is not available. ...

There is a streamline option in the gear menu. Does that not work? You can e-mail me a sample file. To include the data you can take a snapshot of the input (in the gear menu - General submenu).
