Chart
Component Palette Icon:
The Chart component (also called the Classic Chart when contrasted with the Easy Chart) provides a flexible way to display either timeseries or X-Y charts that are powered by any number of datasets. Typically, these datasets are bound to SQL Query Bindings.
Features
-
SQL Query and/or SQLTags Historian data sources
-
Zoom, Pan, X-Trace modes
-
Any number of Y-axes and subplots
-
Realtime or Historical
-
Many different rendering styles
Configuration
The basic idea behind configuring the class chart is simple: add datasets, and fill them in with data in a format that the chart understands. You add datasets to the chart using the chart's customizer. You then use standard property binding to put data into these charts. Commonly you'll use a SQL Query Binding. Since these datasets are just normal dynamic properties, you can also access them via scripting.
The Customizer also lets you add additional X and Y axes. There are various types of axes, and they each have a large number of properties. Lastly, you can configure additional properties for each dataset, such as which axes it maps to, its visual style, subplot, etc.
Datasets
Each dataset should define one or more "series" (a.k.a "pens"). The format for these datasets is quite simple. Each series in a dataset shares common X-values, defined by the first column. Each additional column are the Y-values for a series.
Binding Techniques
The classic chart can be used to make almost any kind of chart, with some effort. Historical, realtime, dynamic pen selection, etc is all possible. Your job is just to fill the datasets with the pertinent data, and the chart will display it. The most common idea is to make the chart dynamic by varying the date range that the dataset's SQL Query bindings run. This is easy to do by adding a Date Range component and using Indirect Bindings.
Chart Type: XY vs Category
The classic chart is typically in XY Plot mode. This means that the x-axis is either date or numeric, and the y-axes are numeric. If your x-axis is categorical (names, not numbers), you can switch theChart Type property to Category Chart. Don't be surprised when you get a few errors - you'll need to go and switch your x-axis to be a Category Axis, and fill your dataset in with valid category data, that is, String-based x-values. This is most often used with the bar-renderer (see the Customizer).
