90.956  Summaries.--When it is not convenient to examine in court the contents of voluminous writings, recordings, or photographs, a party may present them in the form of a chart, summary, or calculation by calling a qualified witness. The party intending to use such a summary must give timely written notice of his or her intention to use the summary, proof of which shall be filed with the court, and shall make the summary and the originals or duplicates of the data from which the summary is compiled available for examination or copying, or both, by other parties at a reasonable time and place. A judge may order that they be produced in court.
