ColumnSeries Chart disappear after showing the tooltip with the column value

[Ramón Esteban]

Hi,

I don't know why but setting the ToolTip enable for my column data is causing the entire chart to disappear. Here's my code to load the Chart Columns:

In my Fragment:

var chartService = Mvx.Resolve<IChartService> ();

frame_basket = view.FindViewById<FrameLayout> (Resource.Id.frame_basket);
frame_basket.AddView(chartService.GetBasketSizeColumnChart(this.Activity, IndicatorsVm.BarsData.ElementAt(0)));  

The GetBasketSizeColumnChart function is defined:

#region GetBasketSizeColumnChart

        public View GetBasketSizeColumnChart (Context context, CurrentMonthIndicator indicator)
        {
            SfChart chart = new SfChart(context);
            chart.SetBackgroundColor(Color.White);

            chart.Legend.Visibility = Visibility.Visible;
            chart.Legend.ToggleSeriesVisibility = true;
            chart.Legend.DockPosition = ChartDock.Bottom;

            CategoryAxis categoryaxis = new CategoryAxis();
            categoryaxis.LabelPlacement = LabelPlacement.BetweenTicks;
            categoryaxis.Title.Text = indicator.Name;
            chart.PrimaryAxis = categoryaxis;


            // Calculate the numerical axis
            var max = System.Math.Max(indicator.RealValue, indicator.TargetValue);

            NumericalAxis numericalaxis = this.GetNumericalAxis (max);
            chart.SecondaryAxis = numericalaxis;

            // Real data
            ColumnSeries columnSeries1 = new ColumnSeries();
            columnSeries1.Label = context.Resources.GetString(Resource.String.sales_indicators_real);
            columnSeries1.LegendIcon = ChartLegendIcon.Rectangle;

            var dataReal = new ObservableArrayList();
            dataReal.Add(new ChartDataPoint(context.Resources.GetString(Resource.String.sales_indicators_real), (double)indicator.RealValue));
            columnSeries1.DataSource = dataReal;


            // Target Data
            ColumnSeries columnSeries2 = new ColumnSeries();
            columnSeries2.Label = context.Resources.GetString(Resource.String.sales_indicators_target);
            columnSeries2.LegendIcon = ChartLegendIcon.Rectangle;

            var dataTarget = new ObservableArrayList();
            dataTarget.Add(new ChartDataPoint(context.Resources.GetString(Resource.String.sales_indicators_target), (double)indicator.TargetValue));
            columnSeries2.DataSource = dataTarget;

            chart.Series.Add(columnSeries1);
            chart.Series.Add(columnSeries2);

            columnSeries1.TooltipEnabled = true;
            columnSeries2.TooltipEnabled = true;

            return chart;
        }

        #endregion 

Once the animation of the tooltip finished the chart is reloaded somehow with no data.

Am I doing something wrong?

I have attached couple of images with the results.
