Marked data points can be displayed using a graph. There are several types of displays available. Each has its specific settings.
===== Graph Control =====
{{ :cs:mervis-scada:90-how-to:36.png |}}Graph Control Icon
Graph control is common for all types of graphs and allows:
| {{:cs:mervis-scada:90-how-to:01-project-graph.png |}} |Hide legend|
| {{:cs:mervis-scada:90-how-to:02-project-graph.png |}} |Abbreviated legend (only the name of the data point)|
| {{:cs:mervis-scada:90-how-to:12-project-graph.png |}} |Full legend|
| {{:cs:mervis-scada:90-how-to:03-project-graph.png |}} |Hide axis labels|
| {{:cs:mervis-scada:90-how-to:14-project-graph.png |}} {{:cs:mervis-scada:90-how-to:04-project-graph.png |}} |Select points / Delete selected points|

===== Line Graph =====
This is the most commonly used type of graph. In most cases, the desired information can be found in this display. It is especially suitable for comparing multiple variables over time.

2 Legend
{{ :cs:mervis-scada:90-how-to:29-project-graph.png |}}Legend
By clicking on the legend, it is possible to show/hide data assigned to it. Labels are also pinned directly to the time axis.
3 Weekend Marking
Gray background marks Saturday and Sunday.
===== Carpet Graph =====
Suitable for detailed display of 1 variable over a longer time period (e.g., 1 month). This graph is useful for status variables, where the device's mode can be displayed for individual days in the selected period. This way, other variables (e.g., room temperature) can also be displayed.
{{ :cs:mervis-scada:90-how-to:30-project-graph.png |}}Current operating mode of the heating circuit. On the x-axis, individual days of the displayed period are visible. On the y-axis, hours in the day are visible.

2 Weekend Marking
Vertical white lines separate the workweek, Saturday, and Sunday.
3 Color Scale Legend
4 September 28th was a public holiday. In the graph, it is clearly visible that the weekend operation was observed
===== Modulo Graph =====
The Modulo graph is suitable for displaying a "characteristic" profile - profiles from time-matched periods (days, weeks, etc.) are displayed on top of each other, making it easy to identify significant deviations from the typical profile.
{{ :cs:mervis-scada:90-how-to:31-project-graph.png |}}Instantaneous power
1 Time Period Settings
In this type of graph, it is possible to set the period to weeks, months, or years.
2 Graph Labels
Display: date, time, value, and data point name
===== Column Graph =====
This is the second most commonly used type of graph. It is suitable for displaying variables for which some aggregation (average, maximum, minimum, etc.) is appropriate.
