A web app I am working on uses ag-grid to render detailed status data in a grid. Customer wants to chart a comparison between planned and actual status values, which I was able to do quickly and easily with ag-grid's charting capabilities. However, after a review the customer is interested in displaying the line as stepped between points rather than linear since each point is a target and data between targets is not interpolated in the details. I assumed that line interpolation was a fairly standard (and common) option for rendering line charts and would be supported. However, I cannot seem to find an option which allows me to set the line interpolation or stepping.
Am I just missing an option or is line interpolation and stepping just not supported for ag-grid line charts? If it is not supported, can this be done through some kind of customization, or am I stuck either adding points to my line to make it kind-of-sort-of look like a stepped line or pulling in a whole other charting library for what seems like a basic function?

Today I'm having trouble explaining to a user why it's better to use Cognos than Excel.
For any visualization type in Cognos (Charts, Legacy visualizations, 11.0 visualizations, 11.1 visualizations) is there a way to make a line chart that uses line styles rather than line colors? I have a requirement for a viz that is copyable (in black and white) and readable by anyone with any color vision problem. The charts in question are typically limited to only a few lines, so one solid, one dashed, one dotted and one with a dot-dash pattern would work fine. I am not finding this capability.
I'm working on generating some figures for a paper from a simulink model, and would prefer to use minimal work to produce them so I'm trying to configure a simulink scope to output the figures I want on its own. The problem is, while I can get colors and such all arranged well, I can't seem to figure out how to modify the spacing between the graphs in a scope showing multiple signals. What I have now looks like the below:
Notice how the two plots have different vertical scales (probably a consequence of having the time scale only on the bottom one), and that there's a large gap of unused space between the plots. This is a concern when trying to publish in a journal, since page space is at a premium and we need to make the information as dense as possible.
So, how can I tweak these margins and formatting? I've tried looking at all the settings I can find, but none seem to affect these parameters.
I'm using Mapbox Studio to label some point features (from a GeoJSON layer I uploaded) in a style, and there are some duplicate points located nearby each other:
Are there any options in Mapbox Studio to remove the duplicate labels automatically? For example, some other mapping programs have the option to remove duplicate labels within a specified distance (pixels or map units). Is this available in Mapbox Studio (or failing that, in Mapbox-GL-JS)?
Mapbox Studio does not provide a way to remove the duplicate labels automatically. You could work with a filter to manually filter out duplicates by writing a relatively complex expression, although this is not really the intended use case of expressions. You could also add a duplicate: true property to duplicated point features in your source data, but since this would require manipulating your source data, you might as well remove the duplicates from the source data instead of taking this approach.
That being said, you could consider clustering your data and styling the clusters so that a cluster looks the same as any individual point. This example shows how to create and style clusters using Mapbox GL JS. Here is a JSFiddle that heavily modifies this example to cluster closely-located points, and style the clusters in the same way that individual points are styled: https://jsfiddle.net/uo216fxz/ (you will need to add your own Mapbox access token in order to view the result). Text labels are added with the point count for each cluster containing more than one point, so that you can easily see that clusters and single points are identical aside from the labeling.
You will likely need to customize several properties (such as clusterRadius, clusterMaxZoom, etc) beyond what is provided in the linked JSFiddle, to be more specific to your source data.
I've been trying to force a trendline through 0,0 for my scatter graph, but I can't seem to find a way to do this.
From the docs here, they don't give any information on it: https://developers.google.com/chart/interactive/docs/gallery/trendlines
But, I know there are lots of undocumented stuff in charts.
This is an example of what i am trying to do within Google charts(Done within excel)
The red dotted liner is the trendline, on the left is the default liniear regression that Google charts can give, but in many situations you would want to force a Y-intercept, in this example its forced to be at 0
No, you should NOT need values to force an intercept. This is a pretty standard option in graphing programs. Unfortunately, I don't see where Google Sheets gives you the option, which is one reason I don't recommend it for serious data analysis.
It's odd that the LINEST function allows you to force a zero Y-Intercept, but the trend-line tool in the Chart Editor does not. Excel offers a checkbox to force the line through the origin. (Of course, one should exercise caution when doing so. You really have to know something about the data your analyzing.)
I have drawn several bar chart, scatter, and line graphs in SPSS 21 and spent lots of time on editing their look. But, I realized that I made some mistakes in data and they are already changed. In Microsoft excel, graphs are interactive/dynamic, meaning that they change if you modify the values of each cell. Can we mimic the same feature in SPSS 21? Is there any way I can update graphs without redrawing them from the scratch? I have saved them as output, but when I load them no change is reflected and the graphs are associated with old data.
I have saved syntaxes to produce the graphs, but when I run the syntax, the graphs are produced in standard looking that need lots of changes to look good. When I save chart templates and apply them to new charts, they don't look the same meaning that some of the changes are not applied.
Please help.
It is not possible. I feel you with making all the changes and the inconsistency in applying chart templates though. A few tips to mitigate this in the future are;
Do everything you can with GGRAPH and inline GPL statements to get the look of the chart close to how you want it.
Start with a chart template that is closer to your typical end goals. (See here on how to make some simple edits to the default template).
Some things are still difficult to fully automate like label placement in the chart. These simple tips though get me very close to the end goal, and only rarely do I need to take the time to polish a chart with editing post-hoc.
