BarSeries Quickstart

A BarSeries plot allows each Bar to be created and customized individually.

var plt = new ScottPlot.Plot(600, 400);

// Create a collection of Bar objects
Random rand = new(0);
List<ScottPlot.Plottable.Bar> bars = new();
for (int i = 0; i < 10; i++)
{
    int value = rand.Next(25, 100);
    ScottPlot.Plottable.Bar bar = new()
    {
        // Each bar can be extensively customized
        Value = value,
        Position = i,
        FillColor = ScottPlot.Palette.Category10.GetColor(i),
        Label = value.ToString(),
        LineWidth = 2,
    };
    bars.Add(bar);
};

// Add the BarSeries to the plot
plt.AddBarSeries(bars);
plt.SetAxisLimitsY(0, 120);

plt.SaveFig("barseries_quickstart.png");

BarSeries Horizontal

Horizontal orientation can be achieved by customizing the IsVertical property of each Bar.

var plt = new ScottPlot.Plot(600, 400);

Random rand = new(0);
List<ScottPlot.Plottable.Bar> bars = new();
for (int i = 0; i < 10; i++)
{
    int value = rand.Next(25, 100);
    ScottPlot.Plottable.Bar bar = new()
    {
        Value = value,
        Position = i,
        FillColor = ScottPlot.Palette.Category10.GetColor(i),
        Label = value.ToString(),
        IsVertical = false, // ENABLE HORIZONTAL ORIENTATION
    };
    bars.Add(bar);
};

plt.AddBarSeries(bars);

plt.SaveFig("barseries_horizontal.png");

BarSeries with Error Bars

Combine a BarSeries plot with an ErrorBar plot to achieve this effect.

var plt = new ScottPlot.Plot(600, 400);

// Create and add Bar objects to the plot
Random rand = new(0);
List<ScottPlot.Plottable.Bar> bars = new();
for (int i = 0; i < 10; i++)
{
    int value = rand.Next(25, 100);
    ScottPlot.Plottable.Bar bar = new()
    {
        Value = value,
        Position = i,
        FillColor = ScottPlot.Palette.Category10.GetColor(i),
        LineWidth = 2,
    };
    bars.Add(bar);
};
plt.AddBarSeries(bars);

// Add error bars on top of the BarSeries plot
double[] xs = bars.Select(x => x.Position).ToArray();
double[] xErrs = bars.Select(x => (double)0).ToArray();
double[] ys = bars.Select(x => x.Value).ToArray();
double[] yErrs = bars.Select(x => (double)rand.Next(2, 20)).ToArray();
var err = plt.AddErrorBars(xs, ys, xErrs, yErrs);
err.LineWidth = 2;
err.CapSize = 5;
err.LineColor = Color.Black;

plt.SetAxisLimitsY(0, 120);

plt.SaveFig("barseries_error.png");
