Type du graphique

The program currently supports the following chart types:

HistogrammesDisplays vertical columns whose heights correspond to the data values.
BarresDisplays horizontal bars whose lengths correspond to the data values.
CourbesDisplays a line through points whose vertical positions correspond to the data values, the horizontal positions are evenly spaced.
SecteursDisplays a circle divided up into regions whose relative sizes correspond to the data values.
AnneauLike the Secteurs chart but displays one or more series.
X-YDisplays a line through points whose x and y coordinates are given by the data values.
AiresLike the line chart, but the area below the line is filled in, and the series values are stacked.
RadarDisplays a line through points whose distances from a central point correspond to the data values.


Séries du graphique

This allows you to specify the data values to be used for each series. To add a new series, press the Nouveau... button. To change an existing series, select it in the list box and then press the Modifier... button. To remove an existing series, select it in the list box and press the Supprimer button.

Note that for Secteurs charts, only the first series will be displayed.

When entering or changing a series, you are prompted for the following information:

DonnéesNomAn optional name that is used to identify the series in the list box. It defaults to 'Série1', etc.
Y valeurA reference to the cells that contain the data to be charted. You can specify more than one reference, separating them with commas, but they must all be from the same sheet. Alternatively you can specify this as an array of values.
X étiquettesFor Histogrammes, Barres, Secteurs, Courbes and Aires charts, you can specify a reference or array of values that will be used to label the categories. As there is only one set of labels, this must be the same for all the series on one chart. For X-Y charts, this item is labelled X valeur and you must enter a reference or array of values to be used as the x co-ordinates of the line.
MotifsType de traitAllows you to choose a solid, dashed or dotted line.
Couleur de traitAllows you to specify the color of the line.
Type de marqueFor Courbes, X-Y and Radar charts, allows you to choose a marker for the data points.
Couleur de marqueFor Courbes, X-Y and Radar charts, allows you to choose the foreground and background colors for the marker.
Couleur remplissageFor Histogrammes, Barres, Secteurs, Anneau and Aires charts, allows you to specify the colour that will be used to fill the interior.
ÉtiquettesType des étiquettesAllows you to display the x or y values next to the data points, and for Secteurs and Anneau charts the percentages.


Titres du graphique

This allows you to specify the titles that will be used to label the chart itself and the x and y axes. Note that axis titles do not apply to Secteurs charts.


Axes du graphique

This allows you to specify the formatting of the x and y axes. The actual options that are available will depend on the currently selected chart type.

AxeSpecifies whether the axis line will be drawn.
QuadrillageSpecifies whether the guidelines will be drawn.
GraduationSpecifies whether the axis tick marks will be drawn.
ValeurSpecifies whether the axis values will be displayed.
LogarithmiqueSpecifies whether a linear or logarithmic scale is required.
MinimumSpecifies the minimum value to be used on the scale.
MaximumSpecifies the maximum value to be used on the scale.
PasSpecifies the interval between the values on the scale.


Legende du graphique

This allows you to specify the whether and where to display the names that identify each series with its line and/or area color. For Secteurs charts, the information displayed will be the category names (from the 'X labels' entry in the series formatting dialog box), for other chart types it will be the Series names from the chart series list box.
