<h3>Samurai Graph Questions and Answers</h3>

<div class="question">
<h4>Q1: What type of input data can I use?</h4>
A: You can use CSV format text files.
<!--
There are four acceptable data types as 2-dimensional data: Scalar XY,
multiple XY, sampling XY and vector XY.
-->
There are three acceptable data types as 2-dimensional data: Scalar XY,
multiple XY and sampling XY.
Explanation of the file format of each data type is given as follows:

<ul>
<li>Scalar-XY<br />
    This type of data consists of the pairs of X and Y values.
    Samurai Graph can draw lines, symbols and bars for this type of data.
    Together with error values and strings in data, it can draw error bars
    and tick labels additionally.
    For this type of data, there are four possible formats given as follows:
    <ol>
      <li>Two columns of numeric values.
          They are regarded as X values and Y values, respectively.
      </li>
      <li>Four columns of numeric values.
          They are regarded as X values, Y values, the lower and the
          upper error values, respectively.
      </li>
      <li>Two columns of numeric values and one column of strings.
          They are regarded as X values, Y values and strings for the
          tick labels, respectively.
      </li>
      <li>Four columns of numeric values and one column of strings.
          They are regarded as X values, Y values, the lower and the
          upper error values and strings for the tick labels,
          respectively.
      </li>
    </ol>
    In the case of 3 and 4,
    each string in input data must be written between two double
    quotation marks.
</li>
      
<li>Multiple-XY<br />
    The multiple scalar type XY data.
    With this type of data, it is possible to draw multiple lines, symbols and bars.
    The input data must consists of columns of numeric values more than one.
    Values in the first row are regarded as X values, and others are
    regarded as multiple Y values.
</li>
      
<li>Sampling-XY<br />
    This data format is similar to the multiple XY format except that a
    column for X values does not exist.  The input data must consists of
    columns of numeric values, and they are regarded as multiple Y values.
    The X values are generated automatically by the sampling rate entered
    into the wizard dialog when users add this data to the figure.
    The interval is equal to the reciprocal number of the sampling rate,
    and the number of the X values is equal to that of the Y values.
</li>

<!--      
<li>Vector-XY.<br />
    This type of data consists of the set of vectors.
    For this type of data, this plotter can draw a vector diagram.
    The input data must consists of four columns of numbers.
    Values in the first two rows are regarded as X and Y coordinate of
    the starting point of the vectors.
    For the third and the fourth rows, users can select their meaning by
    the wizard dialog when users add this data.
    <ol>
      <li>
          The third values and the fourth value are regarded as the
          magnitude and the angle of each vector in polar coordinate.
          Angle values must be given in units of radian.
      </li>
      <li>
          The third and the fourth values are regarded as the X and Y
          components of each vector.
      </li>
    </ol>
    Note for all cases:
    The length of all columns must be the same.
    Values in each row must be separated by spaces, tabs or commas.
</li>

</ul>
</div>

<div class="question">
<h4>Q2: How do I plot the data?</h4>
A: There are two ways to plot the data.
<ul>
<li>Drag and drop
  <ol>
    <li>Drag and drop the data file into the Samurai Graph window.</li>
    <li>A wizard dialog is displayed. Select the data type and press the
        OK button.</li>
  </ol>
</li>
<li>Tool bar / Menu bar
  <ol>
    <li>Press the button on a tool bar to add data, or execute the command
        [File]-[Draw Graph] in the menu bar.</li>
    <li>Wizard dialogs are displayed successively.
      <ol>
        <li>Select figure ID number and press the Next button.</li>
        <li>Choose a data file and press the Next button.</li>
        <li>Select the data type and press the OK button.</li>
      </ol>
    </li>
  </ol>
</li>
</ul>
Note:
<ul>
  <li>
    When the data is added, Samurai Graph classifies the input data into
    available data types and prompts users to select the data type using a
    wizard dialog, in which only radio button for the acceptable types are
    selectable.
  </li>
  <li>
    If the file is dropped onto the point out of figures or a figure with
    the ID of the user selected does not exist, a new figure is created
    automatically.
  </li>
  <li>
    The legend of data in the figure is automatically generated at the
    first addition of the data.
    It is also automatically updated with each addition, removal of data
    and the change of the appearance of data.
  </li>
</ul>
</div>

<div class="question">
<h4>Q3: How do I move the figure?</h4>

</div>

<div class="question">
<h4>Q:4 How do I resize the figure?</h4>
