zoom performance

Recommended Posts

Is there a way to improve the zoom performance so that at least the crop box shows up faster?  Right now, it takes too much time (5+ seconds) for just the crop box to show up.  Is there something running when I click/drag that I can disable?  I've already turned off AllowDrag, AllowDrop, Highlighting, and ToolTips.

Thanks

here is the relevant component initialization:

this.chart.AllSeries.MarkerShape = ChartFX.WinForms.MarkerShape.None;

this.chart.AxisX.ForceZero = false;this.chart.AxisX.LabelsFormat.CustomFormat = "HH:mm:ss";

this.chart.AxisX.LabelsFormat.Format = ChartFX.WinForms.AxisFormat.DateTime;this.chart.AxisX.Staggered = true;

this.chart.AxisX.Title.Text = "";this.chart.AxisY.ForceZero = false;

this.chart.AxisY.LabelsFormat.Decimals = 2;this.chart.AxisY.LabelsFormat.Format = ChartFX.WinForms.AxisFormat.Number;

this.chart.AxisY.Title.Text = "";this.chart.Border = new ChartFX.WinForms.Adornments.SimpleBorder(ChartFX.WinForms.Adornments.SimpleBorderType.Color, System.Drawing.Color.FromArgb(((int)(((byte)(0)))), ((int)(((byte)(0)))), ((int)(((byte)(0))))));

this.chart.Dock = System.Windows.Forms.DockStyle.Fill;this.chart.Highlight.Enabled = false;

this.chart.LegendBox.Border = ChartFX.WinForms.DockBorder.None;this.chart.LegendBox.ContentLayout = ChartFX.WinForms.ContentLayout.Far;

this.chart.LegendBox.Dock = ChartFX.WinForms.DockArea.Top;this.chart.Location = new System.Drawing.Point(0, 0);

this.chart.Name = "chart";this.chart.Palette = "HighContrast.HighContrast";

this.chart.PlotAreaColor = System.Drawing.Color.Transparent;this.chart.Size = new System.Drawing.Size(1008, 668);

this.chart.TabIndex = 0;this.chart.ToolBar.Visible = true;

this.chart.ToolTips = false;

chart.ToolBar.RemoveAt(4, 2);

chart.ToolBar.RemoveAt(5, 10);

chart.ToolBar.RemoveAt(chart.ToolBar.Length - 2, 2);

chart.ToolBar.RemoveAt(chart.ToolBar.Length - 2, 1);

chart.AxisX.AutoScale = false;

chart.AxisY.AutoScale =

false;chart.AllowDrag = false;chart.AllowDrop = false;

chart.RandomData.Series = numItems; //numItems is usually a few, 1 or 2 usually

ChartFX.WinForms.

SeriesAttributes[] seriesAttribArray = new ChartFX.WinForms.SeriesAttributes[numItems];for (int k = 0; k < numItems; k++)

{

seriesAttribArray[k] = new ChartFX.WinForms.SeriesAttributes();

}

chart.Series.AddRange(seriesAttribArray);

chart.Data.Points = numPoints; //numPoints is less than or equal to 86400

//now put in points

chart.AxisX.Min = min; //min is a precalculated value

chart.AxisX.Max = max; //max is a precalculated value

chart.AxisY.ResetScale(); //autoscale the Y axis

Now I call the Show() method of the form from another form.

 

Maybe the slow performance is an isolated case with Vista?
