<pre wrap="">Kst,
Here are some features I would love to see in Kst...
*
Scroll Bar *- It would be great to have a scroll bar at the bottom of each
plot. This will give the user a perspective on where they are when zoomed
into a small window of a large data set. SensorCloud uses this
functionality, if you haven't seen it (it's very impressive) you can view
it in action here <a class="moz-txt-link-freetext" href="https://www.youtube.com/watch?v=T6tko2wOJc4">https://www.youtube.com/watch?v=T6tko2wOJc4</a>.

Hmmm.... this doesn't really fit into kst's model (where consumers of vectors
neither know nor care where the vector came from). And one might have a plot
which shows data from multiple datasources of different sizes and of different
ranges. So it is hard to understand what the scroll bar would refer to in
this case.
So... hmmm... let me think about it and see if I can come up with a
coherent/consistent model.</pre>

It seems to me that this feature should work even when data sources
are of different sizes and with different ranges. Ultimately the
plot has a finite range with a first x-axis sample and a last x-axis
sample. The scroll bar just shows what portion of the full range
(from first to last sample) is currently in view.<br>
<br>
When zoomed into a large data set it is easy to loose perspective.
It can be difficult to tell how much progress is being made when
scrolling backwards and forwards e.g. If I keep scrolling at this
rate will I get through this data set in 5 minutes of five hours? Or
I'm looking for an event that occurred about 3/4 through the test,
is it likely to be forward or backward from my current position.<br>
<br>
As an added feature, the scroll bar could be manipulated to control
the view in the main plot area. The active portion of the scroll bar
could be paned backwards and forwards (maintaining a fixed range) or
the edges of it could be moved to expand or contract the current
view (variable range).<br>
<br>
WRT your suggestion of using a graphical version of the change range
dialog. I don't this this is what I'm looking for. For this feature
to be useful it needs to be quick. I'm pretty sure the change range
feature will trigger a new read of the data source(s) which is on
the intent of this feature. It's more about being able to move
quickly around the currently loaded range.<br>
<br>
I'm not sure how Kst works behinds the the UI so I may be way off
track here and happy to be corrected.<br>

<pre wrap="">*Digital Display* - Sometimes it is handy to have the current value of a
channel shown as a digital number. It is much quicker and more accurate to
read a number off a digital display rather than interpolate the value off a
plot. HBM's Catman software has this feature and a really nice touch is
that you can configure the display to show one of the channels statistical
values when live data is stopped. So when live data is streaming it will
show the current value but when live data stops it will display the
channels min, max, average or other such value. This is a really handy
feature and can save a lot of time. You can see this feature in action here

If I understand what you mean: We can already do this.
Create a curve - say ploting [ALT (V2)] vs [Time (V1)].
Create a label.
As the label text use: Sensor: [ALT:Last (X15)] m
When you type "[" in the label text box, a large auto completion box will
appear with all of the possible scalars and strings that you can insert. The
list includes First, Last, Sigma, Mean, rms, Max and Min and a few other
things for each vector.
You can also do equations in labels:
For example, [=[ALT:Sigma (X18)]^2] would give the square of the standard
deviation.</pre>
</blockquote>
Cool! I didn't know you could do that.<br>
<br>
This is very close to what I'm looking for. It just seems a bit odd
to put this sort of information in a label. Especially if there are
a number of variables to keep track of (see RH label in screen shot
below). It would be great if there was a "text box" with this sort
of functionality that could be positioned just like the legend can.

<pre wrap="">*Set Default Update Type* - On the first screen of the data wizard the user
can choose the desired update type - time interval, change detection or no
update. The default is change detection. Once an update type has been
selected for a particular file, Kst will remember this, which is great. But
for a new file the user is forced to change this setting every time, if
they wish to use a setting other than change detection. It would be great
if the default setting could be changed somewhere.

Definitely - I will add this. You can add a wishlist bug for this so I don't
forget :-)</pre>
