OEE chart settings

Set options for OEE (Overall Equipment Effectiveness) chart types.

Note: OEE charts settings and all other settings in the Chart overrides node on the Settings dialog can be saved as a chart skin. See Chart Skins for more information.

Navigating to these settings

On the Settings dialog

Follow this path on the Settings dialog:

Chart overrides | Charts | OEE chart options

On the Systems Administration module (default settings for charts, if you have permissions)

Follow this path on the Configuration tab of the System Administration module:

Configurations | "Configuration" | Chart defaults | OEE charts

OEE chart options

Setting goal colors example:

• The Target Colors > Background Color bands options button must be selected to enable these settings. See Goal and Acceptable targets below in this topic for more information.

Color for Above Goal =

Change the background color for the chart zone above the line set for the goal.  

Color for Below Acceptable =

Change the background color for the chart zone located below the line set for Acceptable data. The GainSeeker default setting is (LightCoral).

• For information about determining the goal and acceptable target zones, see Goal and Acceptable targets below in this topic.

Color for Between Goal and Acceptable =

Change the background color for the chart zone for acceptable data, data that plots below the Goal zone and above the Acceptable zone. The GainSeeker default setting is (NavajoWhite).

• For information about determining the goal and acceptable target zones, see Goal and Acceptable targets below in this topic.

Display bars for OEE charts

Select this check box to display bar charts, or clear it to display line charts.

Any of the following scenarios will also cause OEE charts to be displayed as bar charts, regardless of this setting:

• the chart is an OEE Combined Chart

• the primary grouping on the chart is Traceability

• there is secondary grouping on the chart

• the chart is limited to the top/bottom n values

Display values for OEE charts

When this check box is selected, the percentage value is displayed for each bar on the OEE chart. When it is cleared, the percentage is not displayed for each bar.

This setting does not apply when OEE charts are displayed as line charts. For more information, see Display bars for OEE charts.

Goal and Acceptable targets

Set percentage values between 0% and 100% to display goal and acceptable limits horizontal lines on charts. These setting can help gauge improvement and tell you when any of the submetric percentages for OEE, Availability, Performance, or Quality fall below set historical values, for example. Some of the settings have GainSeeker default values set that you can change; others have no default values.

• Also see Color for above Goal, Color for below Acceptable, and Color for between Goal and Acceptable settings.

• OEE Available Statistics

Group data for OEE chart by =

Group data by a specific time period or by a traceability item you select for OEE charts. Then, you can optionally select second-level grouping to display data grouped by both as bar plots on a single chart.

• See Grouping data on OEE charts for more information.

Note: This setting can be located following this path on the Settings tab:

Retrieval/Configuration | Group data for OEE chart by

OEE Chart y-axis high scaling =

Use this setting to set the high value for the y-axis percentage range.

The y-axis on an OEE chart displays a percentage that ranges between 0% and 100%, depending on where the data plots. You can set the y-axis to always display a specific percentage value at the high and/or the low end. Setting a specific percentage range (75% and 100%, for example) can be used to normalize the chart scaling, making variance more easy to view for data that may plot in wide ranges.

OEE Chart y-axis low scaling=

Set the low value for the y-axis percentage range.

The y-axis on an OEE chart displays a percentage ranging between 0% and 100%, depending on where the data plots. You can set the y-axis to always display a specific percentage value at the high and/or the low end. Setting a specific percentage range (75% and 100%, for example) can be used to normalize the chart scaling, making variance more easy to view for data that may plot in wide ranges.

Take lost time into account when calculating OEE Quality

Change the default method GainSeeker uses to calculate the OEE Quality metric.

By default, GainSeeker takes lost time into account when calculating the OEE Quality metric. This can tell you how much time was lost in producing defective parts—those that do not qualify as first-pass yield. The calculation GainSeeker uses is Quality % = Time to Produce Good Parts / Time to Produce Total Parts

To change the default setting so that GainSeeker instead calculates the percentage of produced good parts relative to the total number of produced parts (the calculation GainSeeker will use is Quality = Good Parts Produced / Total Parts Produced), deselect the checkbox preceding the Take lost time into account when calculating OEE Quality.

See the OEE "Quality" metric for more information and examples on both settings.

Target Colors

By GainSeeker default, there are horizontal zones on OEE charts for goals and acceptable limits feature colors, such as in the example below.

• The Background color bands setting displays zone colors for both line and bar charts.

• The Color the plot points (bars) setting displays bar colors according to how the data plots against goal and acceptable target values. It uses the zone colors for the bars, but no background zone colors are used as shown in the image below. This setting is not used on OEE Combined or line charts. It only applies to OEE bar charts.

• You can also select None to show no background colors on line and bar charts and no colored bars on OEE bar charts.

Also see Goals and Acceptable targets setting

Top / Bottom n Values

Temporarily display only the top n or bottom n values on an OEE bar chart.

When the data is sorted by date, the bars display on the chart by the value order instead of by date.

Note: When Show top n bars or Show bottom n bars is selected for an OEE chart with second-level grouping, the data does not group to properly reflect the second-level setting.

Displaying only the top n values when you track multiple machines, for example, can help you quickly identify your machines with the least problems.

• Double-click the setting to open the Top/Bottom n Values dialog.

• Select the option button to show the top, bottom, or all bars. Then, choose the number of bars to display for your selection.
