See character replacement below ## Quick Start A diagram definition uses a `Markdown` like syntax called `Mermaid` This is a simple flow chart definition - ``` graph LR A --> B ``` Producing this graph  Supposing you have 2 series with aliases `A-series` and `B-series` In the diagram plugin, you can modify the definition to match the identities of the data -  ## Character Replacement The following characters in metric names are automatically replaced with an underscore. ``` " , ; = : { } ``` ### TODO You can add additional metric replacements in the Display tab, under the section Metric Character Replacement: A single character can be specified or a regular expression, along with the text to be used for the replacement (the default is underscore). ## Examples ### With Subgraph  ### With custom shapes, aliases, and icons ``` graph LR LB[Load Balancer] -- route1 --> web1 LB[Load Balancer] --> web2 web1 --> app1(fa:fa-check app1) web1 ==> app2 web2 ==> app2(fa:fa-ban app2) web2 --> app1 app1 --> D[(database)] ```  ### Field Options  ### Field Overrides  ### Custom Theme  ### CSS Override  ### Using Variables <img src="https://raw.githubusercontent.com/jdbranham/grafana-diagram/grafana-7x/docs/variables.gif?raw=true" width="800px"/> ### Using background as indicator  ### Options * Thresholds [field can override] * Aggregation Options [field can override] * Unbound Color Levels [field can override] * Value mapping to text [field can override] * Unit Format [field can override] * Value of metric to display (min/max/mean/last/) [field can override] * Decimal precision [field can override] * CSS Override * Indicator as background or text color * Theme reactive * Theme customization * Variable replacement in the diagram definition ### Link Metrics Mermaid Notation is the same, but now supports supplying a metric name in the "text". Specify the metric name in double quotes (for escaping purposes). ### Metric Composites To reflect multiple metrics and their thresholds on a single node, use metric composites to specify a composite name, and the metrics to be evaluated for the composite. Series/Field specific overrides will be evaluated for each metric, and the "worst" state of the composite is displayed. The composite name is evaluated in the Diagram definition.  For example, combining two series "A-series" and "B-series" into a single composite named "xyz", the following can be used: When data is received for each series, the thresholds will be evaluated to find the "worst" threshold level, and the metrics and color value will be reflected in the "xyz" composite in the diagram. Here are examples of the composite in action: This diagram has "xyz" node, with "all green" threholds for both series A and B:  This diagram has "xyz" node, where the A-series is green, but B-Series is yellow. The diagram node shows yellow, along with the value:  This diagram has "xyz" node, where the A-series is green, but B-Series is red. The diagram node shows red, along with the value:  This diagram has "xyz" node, where the A-series is yellow, and B-Series is green. The diagram node shows yellow, along with the value:  ### Value or Range to Text Mapping Value and range mapping can be used to replace numeric values by human readable text. In the diagram the value of the matching series will be mapped to text:  ## Roadmap - Custom character replacement - Implement the Hash Prefix Notation Processor?? [New field mapping may replace this] - Remote Diagram Definition URL - [suggest something] ## Development [See Here](https://github.com/jdbranham/grafana-diagram/tree/grafana-7x/docs) ## Thanks!
