Constructor Detail

HistogramOutputPanel

public HistogramOutputPanel(MainControl mainControl)

Creates an instance.

Parameters:

mainControl - the main control of Graphana

Method Detail

setVisualSettings

public void setVisualSettings(boolean linesMode,
                              boolean fatLines,
                              boolean logScale,
                              boolean beginAtZero)

Sets some visual properties.

Parameters:

linesMode - if true, lines are drawn instead of bars

fatLines - if true and linesMode is true, then the lines are thicker

logScale - if true, a log scale will be used for the Y-axis

beginAtZero - if true, the first value on the X-axis is always 0. If false, then the first value of the X-axis is the first value with a non-zero Y-value.

getHistogramCount

public int getHistogramCount()

Returns the number of histograms set.

addHistogram

public void addHistogram(Histogram histogram)
                  throws java.lang.IllegalArgumentException

Adds the given histogram to the view. The histogram will be displayed together with prior added histograms.

Throws:

java.lang.IllegalArgumentException - if there was at least one histogram added before and the given histogram has an x-scale other than the previously added histogram.

addHistogramByString

public void addHistogramByString(java.lang.String csv,
                                 java.lang.String separator)

Creates a histogram by using the given CSV file and adds it.

Parameters:

csv - the CSV string to create the histogram

separator - the separator of the values of the CSV string

clearHistograms

public void clearHistograms()

Removes all histograms.

setHistogramColors

public void setHistogramColors(java.awt.Color[] colors)

Sets the colors of the histograms, whereas the first color is for the first added histogram, the second for the second and so on. The array can be larger than the number of added histograms. If there are more histograms than colors, then modulu the array length is used for indexing the colors.

getHistogram

public Histogram getHistogram(int index)

Returns the histogram with the given index. The first added histogram has index 0, the second 1 and so on.

getInnerPanel

public view.histograms.HistogramOutputPanel.InnerPanel getInnerPanel()

Returns the inner visualization panel.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent ev)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent ev)

Specified by:

stateChanged in interface javax.swing.event.ChangeListener
