Axiom List Box Script to Show/Hide Trend Graph Trend

Hey timothy. vertin , I did the same exact thing! I made sure the items in the List Box have identical names to the Display Names of the Trends. Then, every time a selection changed, I looped through the Trends and toggled IsVisible on the Trend based on if selectedItems.Contains.

        public void LB_ServerSelector_OnSelectionChange(object sender, string[] selectedItems)
        {
            var controls = Screen.ScreenControls as IReadOnlyControlCollectionWithModifiedEvents<IControlBase>;
            foreach (ControlBase control in controls) {
                if (control.Kind == ControlKind.TrendGraph){
                    var graph = control as ControlTrendGraph;
                    foreach (ControlBase graphChild in graph.Children){
                        var trend = graphChild as ControlTrend;
                        trend.IsVisible = selectedItems.Contains(trend.DisplayName);
                    }
                }
            }
        }

        public void B_All_OnClick(object sender, EventArgs eventArgs)
        {
            var list = Screen.ScreenControls["LB_ServerSelector"] as ControlListBox;
            list.SelectedItems = list.Items;
        }

        public void B_None_OnClick(object sender, EventArgs eventArgs)
        {
            var list = Screen.ScreenControls["LB_ServerSelector"] as ControlListBox;
            list.SelectedItems = new string[0];
        }

Oh, you do have to be careful with Scales. If you have all the scales together tied to a single trend, and you uncheck that trend, the scale goes away for everyone. Here's a slightly more complicated version. All the trend's scales are still tied to the first trend. But only the first selected trend in the ListBox has IsScaleLeftVisible set to true. If that makes sense.

        public void LB_WellSelector(object sender, string[] selectedItems)
        {
            bool graphScaleIsVisible = false;

            ControlTrendGraph trendGraph = Screen.ScreenControls["TG_Wells"] as ControlTrendGraph;
            foreach (ControlBase graphChild in trendGraph.Children){
                var trend = graphChild as ControlTrend;
                trend.IsVisible = selectedItems.Contains(trend.DisplayName.Replace(".Separator","").Replace("_"," "));
                if (!trend.IsVisible) continue;

                // Make sure only the first selected trend has their scale visible
                if (!graphScaleIsVisible) {
                    trend.IsScaleLeftVisible = true;
                    graphScaleIsVisible = true;
                } else {
                    trend.IsScaleLeftVisible = false;
                }
            }
        }

        public void B_All_OnClick(object sender, EventArgs eventArgs)
        {
            var list = Screen.ScreenControls["LB_Wells"] as ControlListBox;
            list.SelectedItems = list.Items;
        }

        public void B_None_OnClick(object sender, EventArgs eventArgs)
        {
            var list = Screen.ScreenControls["LB_Wells"] as ControlListBox;
            list.SelectedItems = new string[0];
        }
